The subject matter described herein relates generally to processes for making multiple component board frames capable of providing for efficient transition of frame support for hooping devices used in embroidery applications. More particularly, it relates to improved methods for making such devices which permit precision in all dimensions and quick and easy transition between various hooping applications.
While traditional hooping mounting frame apparatuses were noted for their complexity, see, e.g., U.S. Pat. Nos. 4,545,127; 4,805,297; and 5,432,990; applicant had previously developed a single board apparatus which offered a range of sizes and shapes for embroidering. See U.S. Pat. No. 5,934,210, “Embroidery Board Supporting Hoops”, the full content of which is incorporated herein by reference as though fully set forth herein.
Applicant has developed an improved process for constructing an embroidery framing device which provides for enhanced precision of dimensions, improved durability and greater efficiency of use for diverse purposes when the constructed board is utilized to set up hoops to frame fabric for embroidery.
Accordingly, applicant has developed a process for improved precision, durability and efficiency for a multi-use hoop framing board and/or accessories.
A process for making a precision multi-use hoop framing board and accessories, if accessories are included, is provided. The process includes the step of obtaining precision cut and drilled extruded acrylic and polypropylene, or material of similar qualities (hereinafter referred to as “acrylic and propylene”) embroidery board pieces and hardware for assembling a multi-use hoop framing board. The process further includes printing one or more of the board pieces to provide for pre-determined alignments and utilization indications of the embroidery board pieces to create desired operating units. The process also includes the step of assembling the multi-use hoop framing board from the printed board pieces and hardware.
In a further embodiment, the process includes the step of using a CO2 laser cutter to precision cut the extruded acrylic and polypropylene pieces.
In yet an additional embodiment, the process includes preparing accessories for the multi-use board frame including at least a leveling aid for assistance in placement of hooping devices at various locations on the framing board.
In a further embodiment, the process is divided into making pre- and post-shipment, or sale, sets of components for assembly so that the multi-use hoop framing board and accessories are allowed to be shipped in shipping packaging which is more compact and takes up less space, and, therefore, is less costly to ship.

Referring to the drawings, in one embodiment of the invention, a multi-use hoop framing board 100 may be seen in
In the embodiment shown in
Other components and accessories for the multi-use framing board 100 will be identified in the description of the process of making the framing board outlined below.
An embodiment of the process for making a precision multi-use hoop framing board according to the invention includes the step of obtaining precision laser cut and drilled extruded acrylic and polypropylene embroidery board pieces, together with hardware specific for enhanced assembly of such a precision cut hoop framing board. Alternatively, the process can include the steps of precision laser cutting of the acrylic and polypropylene board pieces and drilling the pieces so that they may be constructed to exacting standards using the predetermined hardware designed for piecing together the hoop framing board.
A main plate 110 of extruded acrylic is obtained to manufacture the framing board 100. Extruded material is preferred for use, e.g., over cast material, because applicant's invention provides for a very consistent thickness throughout the dimensions of the main plate 110, and its machining holds to a tighter thickness tolerance. This observation applies throughout for the various sheet components used in constructing the framing board and accessories mentioned herein.
For the main plate 110, the thickness of the acrylic sheet is from one-half″ to 1″, preferably from ⅝ to ⅞″, and most preferably ¾″ with continuous gradations between these dimensions contemplated. In a further embodiment of the method of the invention, the process involves utilizing a CO2 laser cutter A which applicant discovered gives a most exacting precision cut to extruded acrylic and polypropylene pieces.
In a preferred embodiment, a 4′×8′, or other appropriately-dimensioned sheet of the extruded acrylic is first sized down by saw cutting or other standard means for the laser cutting. The extruded material is preferably double masked with thin protective paper sheets 111a and 111b, front and back, to help protect it during the material preparation and laser cutting process. The top layer sheet 111a is peeled back during the actual laser cutting (see
The sleeve board 20 component is also cut from clear extruded acrylic of the same dimensions as the main plate 110 and after laser cutting has its second (underside) protective surface peeled away. Preferably, the sleeve board is then flamed to ease the sharpness of the sleeve board's edges in readiness for a screen printing process. To prepare the sleeve board 20 for the screen printing process, the sleeve board 20 must be clean and must have tension applied in order to then be coated with selected emulsions that will allow the films of two or more different colors to be exposed onto the screens. After the screens are rinsed and cleaned, they are ready to be installed into the screen printing presses. The machine is adjusted to the thickness and area of the print. The part is then printed, preferably in two colors, (e.g., black & red) one at a time, to register the holes & outside shape with a print tolerance of +/−0.030″, preferably +/−0.015″, with continuous gradations between these dimensions contemplated.
In an embodiment, ultra violet ink may be used and cured under ultra violet lights in a drying rack. A blank after undergoing UV treatment can then be masked to protect it during the laser cutting process. The blank may then be cut using a CO2 laser A, which cuts through the material and in the process creates a polished edge to the part and cuts.
A depiction of the layout of a preferred laser cutting session of the parts in an embodiment of the multi-use framing board main plate 110 are shown in
A useful accessory for the multi-use hoop framing board is a leveling unit 200, which serves to provide a leveling frame of reference for placement of the hooping device. This leveling unit 200 also takes form from an acrylic or polypropylene plate which can be first saw cut from a 4′×8′, or other appropriately sized sheet of clear extruded acrylic or polypropylene (of same or similar thickness as for the main plate 110). The plate for the leveler unit 200 is also preferably double masked with thin protective paper sheets 111a and 111b, front and back, to help protect it during the material preparation and laser cutting process. The top layer sheet 111a is peeled back during the actual laser cutting. The blank for the leveler unit 200 can then be peeled on one side and, again, preferably printed in two colors (e.g., black & red) in register to each color within a tolerance of +/−0.030, preferably +/−0.015″, with continuous gradations between these dimensions contemplated. In this embodiment, the blank is laser cut using a CO2 laser A, which readily cuts through the material. Through this process of laser cutting, a polished edge is imparted to the parts and the laser cuts with a +/−0.010″, preferably with a +/−0.0075″, and most preferably with a +/−0.005″ tolerance as to the size of the part and within +/−0.030″, preferably +/−0.015″ to registration of the printing, again, with continuous gradations between these dimensions contemplated. A photographic depiction of a laser cutting session showing where leveling unit and related pieces are cut from an acrylic blank in a preferred pattern of to form the parts of an embodiment of the hoop leveling unit is shown in
Other sets of parts such as slide locks, extension arms, hoop brackets, as well as variations of leveler parts may be made from polypropylene and may be made from other materials including, but not limited to, PolyEthaline®, Teflon® and Delron®. In preferred embodiments, one set of parts is made from ⅛ to ⅜″, preferably ¼″ white, and the base plate 10 from ⅜ to ⅝″, preferably ½″ black, polypropylene material, again with continuous gradations between these dimensions contemplated. These can also be obtained in 4′×8′ sheets and then cut down in size for the laser cutting. Again, a protective layer of masking preferably is applied to both sides of this blank to help protect it during the laser cutting process. The parts are cut using a CO2 laser A, which cuts through the material with an error margin of +/−0.010, preferably +/−0.075, and most preferably a 0.005″ tolerance, again with continuous gradations between these dimensions contemplated for size for the part.
As mentioned above, in certain preferred embodiments, the process includes preparing accessories for the multi-use board frame 100 such as a “leveler” or leveling aid 200 for assistance in measured placement of hooping devices at various locations on the framing board.
The process also includes the step of making or obtaining precision drilled holes in the extruded acrylic and polypropylene embroidery board and accessory pieces. The process further includes printing one or more of the board pieces to provide for pre-determined alignment of the embroidery board pieces and their use indications to create desired operating units. The process also includes the step of assembling the printed board pieces and hardware into the completed multi-use hoop framing board as illustrated herein.
In an embodiment, precision drilled holes 70, shown in bold in
The complete outside end of all sized units on the main plate 110 of the multi-use framing board 100 is preferably heat polished with map gas.
Using a jig B (see
Drilling and counter sinking of holes 70 in positions shown in bold (see
As shown, the sleeve board 20 includes mounting holes 70 at its top end with vertical slots below the mounting holes 70 to move the sleeve board's leveler arm 21. Thumb screws are engaged in the slots to lock in the leveler arm 21 after its height has been adjusted to a desired location based on a calibration using ruler line numbers to assist in keeping the leveler arm 21 balanced on both its left and right sides. The leveler arm 21 has left and right arm portions which assist in keeping the tubular hoop arm straight. Garment location markings (such as, e.g., letter or symbol indicators) can be printed on the approximately lower third of the sleeve board 20 to assist in garment location. Top and bottom brackets are also inserted into the approximately lower third portion of the sleeve board to hold hoop rings in place. In a preferred embodiment, short vertical slots are drilled into the mid-portion of the sleeve board 20 so that the top bracket can be flexibly re-positioned for differing sized hoop rings. Left and right tubular hoop arm ball rests, previously discussed, are attached to the lower portions of the left and right arms to assist in keeping the hoop arms straight while pushing in the hoop.
A type of jig B for drilling the sleeve board that may be custom made for specific orders or details can be used, but in certain embodiments of the invention, can also be commercially designed. The jig allows the sleeve board 20 to be drilled out with the ⅛″ pin holes 70 in the blocks and main sleeve board 100 which have been printed for alignment and use.
1½″×10-24 flat Phillip's head screws are countersunk in the ½″ black polypropylene material of the, e.g., black base plate 10 to attach the base plate 10 to the braces. The leveler plate accessory, consisting of printed ¼″ acrylic—clear plastic bumpers, is used on the back side for slip protection when placed on the hoop framing board's main plate 110.
Also, on the back side are weld nuts used to work in conjunction with thumb screws. Top and bottom bracket holes 70 are countersunk. Sleeve board leveler arm holes 70 are countersunk and thumb screws secure the leveler arm 21 to the main leveler. On the back side a weld nut is used to tighten the screw in place.
Additional accessories for the multi-use hoop framing board can be included. It should also be noted that one or more components of embodiments of the hoop multi-use framing board and/or accessories such as the leveling unit, hooping devices and other attachments can be added, sold or used separately, e.g., as a replacement part, or the system may be embodied as a set, e.g., where one or multiples of the components are sold as separate units from the rest as a partial do-it-yourself construction set to finish construction from an initial partially constructed or combined “set”. All such methods of constructing the multi-use framing boards and/or accessories and attachments thereto are contemplated as being within the scope of this invention. An exploded view of the component parts 300 are shown in the figures.
