This invention relates generally to apparatus and method for pressing the sleeves of a long sleeve shirt and more particularly, to apparatus and method capable of pressing the sleeves, the pleats and the adjacent areas of the sleeves just above the cuffs during the same pressing operation.
The sleeve of a standard long sleeved shirt is manufactured with a pleat just above the cuff on the outside edge of the shirt while wearing it. This pleat is present due to the fact that the sleeve diameter is larger than the cuff diameter causing the gathering of the material, hence the pleat.
Machines for pressing the sleeves of a shirt are commercially available such as the cabinet style bag sleever Model CSL which has been manufactured and sold by the assignee of this invention, Hoffman-New Yorker, Inc. and which is generally illustrated in U.S. Pat. No. 6,389,716 B1 which is commonly owned by Hoffman-New Yorker, Inc. As illustrated in that patent, those machines generally include a pair of laterally spaced, vertically extending, sleeve bucks with inflatable air bags attached to the front and rear faces of the bucks. At the upper end of each of the bucks is a pneumatically operated T-clamp for holding the cuffs of the shirt in place during a sleeve pressing operation. To press the sleeves, at an accessible loading station, with the back of the shirt facing an operator, the operator passes the shoulders of the shirt over the cuff clamps and the shirt is fully extended downwardly with the sleeves over the bucks. The cuffs of the shirt are positioned under the open T-clamps and the clamps are then closed to lock the cuffs in place with the pleats of the shirt resting against the rear face of the bucks. Low pressure air is then supplied to the air bags to expand the sleeve cavity and remove wrinkles from the sleeves, and the shirt is then tensioned to define the pleats. The bucks are then moved from the loading station to a pressing station within a pressing cabinet and movable steam heated pressing heads are then applied against the sleeves and the bucks for a predetermined period of time under the control of a timer. Upon completion of the timed cycle, the bucks are returned from the pressing cabinet to the loading station and upon movement out of the cabinet the clamps are automatically opened thereby releasing the cuffs. The sleeves and the shirt are then removed upwardly from the bucks. This is generally the manner in which the apparatus illustrated in U.S. Pat. No. 6,389,716 is operated.
When the shirt is removed from the press, the pleat is then pressed by a secondary operation separate from the machine and is normally performed on an ironing board with a hand iron.
It certainly is desirable to be able to press the pleats on the sleeve of the shirt during the same sleeve pressing operation, and thereby eliminate the separate manual pleat pressing operation. This would provide a more efficient, reliable and economical machine and would save substantial time and labor associated with the overall pressing operation.
While the CSL machine illustrated in U.S. Pat. No. 6,497,060 has enjoyed substantial commercial success, applicants have recognized the need to improve the construction and operation of that machine and the invention as described below was developed to satisfy that need.
The primary object of this invention is to provide a novel machine for pressing the sleeves of a long sleeved shirt and the pleated areas of the sleeves just above the cuff during the same pressing operation.
Another object of the invention is to provide the above novel pressing machine which includes separate pleat pressing heads mounted within the pressing cabinet and actuatable to press the pleats as the sleeves are being pressed at the pressing station.
A further object of the invention is to provide the above novel machine wherein the main sleeve pressing heads and pressing bucks are somewhat modified from those used in prior standard machines such as the CSL machine to accommodate separate pleat pressing heads which press the pleats of the sleeves during the same pressing operation.
Still another object of the invention is to provide the above novel machine wherein the pleat pressing heads are operated independently of the main pressing heads of the machine.
It is apparent that applicants' novel machine as described above and its method of operation, eliminate the need to press the pleats by way of a secondary operation such as by using a hand iron and traditional ironing board. In addition, if a shirt does not have pleats, the pleat pressing heads need not be activated and the machine can be used in a conventional manner.
Other objects and advantages of the invention will become apparent from reading the following detailed description of the invention wherein reference is made to the accompanying drawings.
Referring now to
The construction of machine 20 described thusfar is essentially the same as that illustrated in U.S. Pat. No. 6,389,716 except that the upper end 42 of inflatable bag 37 terminates a distance below clamps 40 and 41 to expose the upper portion 44 of rear face 39 of buck plates 35 for a purpose to be described hereinbelow.
Generally speaking, to press the sleeves of a shirt the buck assemblies 22 and 24 are first located at the accessible loading station 28 and, with the back of the shirt facing the operator, the shoulders of the shirt are passed over the cuff clamp assemblies 40 and 41 and the collar of the shirt is pressed downwardly so that the left sleeve of the shirt fully extends downwardly on buck assembly 22 and the right sleeve of the shirt fully extends downwardly on buck assembly 24, with the seams of the sleeves in position over the front air bags 36. The operator then places the cuff under tension clip 101 and the cuff seams on either side of the cuff button plackets behind the pneumatic cuff clamps 43 facing the center of the machine, the cuff clamps then being activated thereby pinning the cuff seams in place. The operator then uses foot pedal 48 to activate a blower which expands the air bags 36 and 37 of each buck assembly 22 and 24. Using the cuff seam clamps and expansion bags 36 and 37 to apply tension, the operator smoothes the sleeves by working the material downward while aligning the sleeve seams on the front bags 36. The tension provided by the operator pulling the sleeves away from the cuff clamps and against the air bags smoothes the shirt sleeves and helps fold and set the cuff seams.
The operator then tensions and smoothes the pleat area of the sleeves above the cuff against the exposed padded portion 44 of rear faces 39 of padded buck plates 35 while further tensioning and reinforcing the pleat folds using the cuff tensioning clips 101 and textured areas provided on the outside surface of air bags 36 and 37. When the sleeves of the shirt are properly dressed on buck assemblies 22 and 24, pan 26 and buck assemblies 22 and 24 are moved rearwardly from station 28 to the pressing station 30 within upper cabinet section 32 wherein buck assembly 22 is positioned in standard fashion between steam heated side pressing heads 50 and 52 and buck assembly 24 is positioned between steam heated pressing heads 54 and 56 in conventional fashion. Heads 50 and 52 and heads 54 and 56 are closable in known fashion upon the sides of the buck plates 35 of buck assemblies 22 and 24 to press the sleeves.
In accordance with this invention, separate pneumatically operated pleat pressing head assemblies 60 and 62 are mounted within cabinet 32 via brackets 64 and 66, respectively, which are fixed to a frame member 68 which is part of the cabinet 34. Assembly 60 is mounted within cabinet portion 32 in adjacent operating relationship with buck assembly 22 and main pressing heads 50 and 52. Similarly, assembly 62 is mounted within cabinet portion 32 in adjacent operating relationship with buck assembly 24 and main pressing heads 54 and 56. Only assembly 62 is shown in
Each pleat pressing head assembly 60 and 62 includes a pneumatic cylinder 70 fastened to bracket 64, a pleat pressing head 72 which has a contoured pressing surface 74 adapted to mate with a contoured rear face 44 of bucks 35. Head 72 is connected to the piston rod 76 of cylinder 70 by a self aligning coupling 77 which includes a coil spring 78 the inner end of which is fixed to piston rod 76 and the outer end of which is fixed to a separate shaft or stem 80 which is fixed to head 72. As shown in
When buck assemblies 22 and 24 are positioned between main heads 50 and 52 and 54 and 56 respectively, as shown in
As already mentioned, the front surface 74 of auxiliary heads 72 is contoured to mate with the upper contoured surface 44 of buck plates 35 to ensure that the pleated area of the sleeves is properly pressed. Also as mentioned, the flexible self aligning coupling 77, which is universally adjustable, also ensures that the contoured surface 74 of heads 72 properly mates with surface 44 to enhance the finishing step for the pleats on the shirt.
It is readily apparent that the invention as described readily accomplishes the objects set forth initially hereinabove. By using the machine of the invention an operator may press the sleeves of the shirt and also the pleated portions of the sleeve located just above the cuffs. This provides for a much more efficient, cost effective, and time saving operation and eliminates the need for separately pressing the pleats of a shirt after the sleeves of the shirt have been pressed as was the common practice with prior conventional machines.
The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
