The present invention relates generally to a method for creating an inlay pattern in a laminate sheet. More specifically, the present invention relates to a method for creating an inlay pattern in a laminate sheet and laminating the inlaid sheet into a composite laminate structure. The present invention finds particular utility for the top skin for a sports board, such as a snow sled or bodyboard.
Laminate sheets are useful in a variety of manufacturing processes. Laminate sheets may be bonded together to form a composite structure having layers of different materials. For example, foam core structures may have protective layers of laminated sheets attached to the outer surface thereof. Typical uses are again, snow sleds and bodyboards.
The present invention provides a method for inlaying a design into a laminate sheet and bonding the inlaid laminate sheet to a core structure or core substrate. The method of the present invention includes the steps of die cutting a preselected inlay design out of a laminate sheet, die cutting a congruent insert to be placed in the aperture left by the die cut design, securing the insert into the die cut design aperture, laminating with heat and pressure the laminate sheet to a core material, and conducting a finishing operation such as trimming to clean the excess laminate sheet from around the edges of the core material.
The present invention is a method for making and applying an inlaid laminate sheet to a core structure or core substrate, and is particularly useful for forming top skin designs on sports boards such as snow sleds and body boards. Top skin material may include polyethylene foam, in the range of about 1/16″ to ¼″ thick, and with a density in the range of about 4-8 lbs/ft3. A first laminate sheet 10 having a die cut inlay periphery or design 12 is shown in
Laminate sheet 10 and laminate sheet 20 are different from one another in at least one material characteristic. For example, laminate sheet 10 may be red in color and laminate sheet 20 may be blue in color. Other color differences may exist between laminate sheet 10 and laminate sheet 20. For example, laminate sheet 10 may be any color and laminate sheet 20 may be any other color including a lighter or darker shade of the same color as laminate sheet 10. The idea is contrasting colors, to enhance the appearance of the laminated sheet.
Other material characteristics may be different between laminate sheet 10 and laminate sheet 20. The surface properties of the sheets may be different. For example, sheet 10 may have a relatively low coefficient of friction and sheet 20 may have a relatively high coefficient of friction. Also the reverse may be true, and sheet 10 may have a relatively high coefficient of friction and sheet 20 may have a relative low coefficient of friction. Variation in the coefficient of friction may be the result of a surface treatment or an inherent material property. Increases in the coefficient of friction increase the purchase, or grip, that the surface has on an adjacent surface.
The matching die cut inlay designs 12 and 22 enable inserts 16 and 26 to be removed from sheets 10 and 20 and interchanged. Replacing insert 16 with insert 26 in sheet 10 makes a laminate sheet having an outer portion 14 of one material characteristic and an insert 26 of another material characteristic. Similarly, replacing insert 26 with insert 16 in sheet 20 makes a laminate sheet having an outer portion 24 of one material characteristic and an insert 16 of another material characteristic. The interchangeability may be used to enhance the characteristics of the composite structure. For example, if the composite structure is a snow sled or body board, an increase in the purchase of a rider surface may enhance the play value of the snow sled. The color of the insert may be different from that of the surrounding expanse, enhancing the visual aesthetics of the sports board.
Laminate sheet 10 may be a variety of polymer materials. For example, polyethylene, polystyrene, polypropylene, and polyvinylchloride may be used to form laminate sheet 10.
A method of making an inlaid laminate sheet and applying it to a substrate, such as the foam core of a sports board, such as a snow sled, will be better understood with reference to
As shown in
Laminate sheet 10 and substrate core 32 are then laminated together, as shown in
It can be seen that tape 30 may be secured in place while laminate sheet 10 is being bonded to substrate core 32 in the laminating device. Tape 30 ensures that inlay piece 26 remains properly aligned and secured in place during the laminating process. As a result of the laminating process, inlay piece 26 and laminate sheet 10 are both bonded in place to substrate core 32. Thereafter, the tape 30 may be removed.
It should be understood that any die cut inlay design may be cut out of laminate sheets 10 and 20, provided two requirements are met. The first is that the design dimensions are contained within the boundary of the exterior edge of substrate core 32. The second requirement is that the design cut out of laminate sheet 10 be substantially the same size and shape as the design cut out of laminate sheet 20. The aperture formed in the die cutting process is maintained within the boundaries of the laminate sheet. This is important because it is necessary to bond the sheet, using the inlay to the substrate core.
After the laminated sheet 10 and inlay piece 26 have been laminated onto substrate core 32, the loose edges of the sheet are “heeled” around the chine and edges of the board, and are laminated to the chine by a heat gun. Excess material is then suitably trimmed away with a knife.
In the process shown, the laminate sheets may be sized about 22″ wide by 46″ or so in length, suitable for snow sled and bodyboard constructions.
The present invention avoids wastage of laminate sheet material in a production process. For example, as a die cut is made on one sheet to create an inlay portion, that first sheet is then available to receive an inlay portion or insert from a second sheet of material. Simultaneously, the second sheet is available to receive an inlay portion from the first sheet or some other sheet having a matching or congruent inlay design.
It should also be understood that the above-described process may be repeated on laminate sheet 20 with inlay piece 16 to form a composite with the material characteristics of laminate sheet 10 in the inlay design and the material characteristics of laminate sheet 20 in the surrounding portion.
The three portions or sections 312a, 312b, and 312c combine together to form the entire die cut design 312. An expanse 314 of top skin 310 is sized to surround die cut design 312. Sections 312a, 312b, and 312c define the boundaries of a set of design inserts 316. Set of design inserts 316 includes a first insert 316a, which is bounded by design section 312a. Set of design inserts 316 includes a second insert 316b, which is bounded by design section 312b. Finally, set of design inserts 316 includes a third insert 316c, which is bounded by design section 312c.
An aperture 318, shown more clearly in
The three portions or sections 322a, 322b, and 322c combine together to form the entire die cut design 322. An expanse 324 of top skin 320 is sized to surround die cut design 322. Sections 322a, 322b, and 322c define the boundaries of a set of design inserts 326. Set of design inserts 326 includes a first insert 326a, which is bounded by design section 322a. Additionally, set of design inserts 326 includes a second insert 326b, which is bounded by design section 322b. Finally, set of design inserts 326 includes a third insert 326c, which is bounded by design section 322c.
An aperture 328 is formed when each of inserts 326a, 326b, and 326c, are removed from within expanse 324, as shown in
It should be noted that die cut design 322 is a congruent to die cut design 312. That is to say that die cut design 312 and 322 are sized and shaped such that each part of the design match. Therefore, insert 316a and insert 326a are sized and shaped to match. Similarly, insert 316b and 326b are sized and shaped to match. Finally, insert 316c and 326c are sized and shaped to match. Because of the congruent size and shape of the inserts, the inserts become interchangeable when producing inlay patterns, as will be explained in more detail below.
As was the case with top skins 310 and 320, a die cut design, or inlay periphery 342 is cut into top skin 340. Die cut design 342 includes three sections or parts. A first section 342a defines a first portion of the design 342. A second section 342b defines a second portion of design 342. A third section 342c defines a third portion of design 342.
The three portions or sections 342a, 342b, and 342c combine together to form the entire die cut design 342. An expanse 344 of top skin 340 is sized to surround die cut design 342. Sections 342a, 342b, and 342c define the boundaries of a set of design inserts 346. Set of design inserts 346 includes a first insert 346a, which is bounded by design section 342a. Set of design inserts 346 includes a second insert 346b, which is bounded by design section 342b. Finally, set of design inserts 346 includes a third insert 346c, which is bounded by design section 342c.
An aperture 348 is formed when each of inserts 346a, 346b, and 346c are removed from within expanse 344, as shown in
It should be noted, similar to as discussed above with reference to die cut designs 312 and 322, that die cut design 342 is a congruent to die cut designs 312 and 322. That is to say that, die cut design 312, 322 and 342 are sized and shaped such that each part of the design match. Therefore, insert 316a, insert 326a, and insert 346a are sized and shaped to match. Similarly, insert 316b, insert 326b, and insert 346b are sized and shaped to match. Finally, insert 316c, insert 326c, and insert 346c are sized and shaped to match. Because of the congruent size and shape of the inserts the inserts become interchangeable when producing inlay patterns, as will be explained in more detail below.

After lamination is complete, a sports board having a composite inlay including insert 326c, 346b, and 326a, has been formed, as shown in
