The system may include a sheet of tape comprised of one-piece with a second side including an adhesive surface; a backing surface removably adhered to the second side of the sheet of tape; a first edge of the sheet of tape being a straight edge; the second edge being a length from a heel area to a toe area of a blade of a hockey stick; the second edge including a concave portion shaped similar to a curve of a top of the blade; the third edge being a length from the heel area to the toe area of the blade; the third edge including a concave portion shaped similar to the curve of the top of the blade; and the fourth edge including two convex portions shaped similar to a toe of the blade.
摘要:
A composite panel (20), which comprises multiple rows of cores (40) and sheets (60). The core rows (40) extend co-directionally along a first direction (X) and are arranged in an array along a second direction (Y). Each sheet row (60) is formed by a sequence of sheets (62) that extend in line along the first direction, and is arranged in-between two adjacent core rows along the second direction. The sheets are folded into U-shapes or Z-shapes around respective adjacent cores, and the sheets within the same sheet row (60) have leading and trailing edges (70, 72) that abut against or overlap with directly preceding sheets of the same sheet row.

摘要:
A process for laminating a material layer to a support including: providing the support, applying the material layer to the support, a heat-activatable adhesive being applied to s side of the material layer facing the dimensionally stable support and/or to the side of the dimensionally stable support facing the material layer, pressing the flexible material layer and the dimensionally stable support together by means of a lower dimensionally stable mold half and an upper dimensionally stable mold half, irradiating the mold halves, the support and the material layer with electromagnetic radiation, in particular with microwave radiation, high-frequency radiation or induction radiation, whereby the adhesive is activated directly or indirectly.

The present disclosure relates to a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. First a resin suitable for making stretch films is selected. Then a dispersed agent is selected, preferably one which has a refractive index similar to the selected resin such that when a film is made comprising the resin and the dispersed agent, the film will appear somewhat clear. The dispersed agent is then mixed with the resin and a film is formed from the resin containing the dispersed agent. Finally, a load is manually wrapped using such film, wherein during wrapping, the film is stretched to a level where the film becomes more opaque.

A method for manufacturing coated profile members (10), wherein a foil (16, 36) is cut to a predetermined width and wrapped around the profile member so as to form a butt seam extending in a longitudinal direction of the profile member, and the foil (16, 36) is cut by a cutting beam (24) in a condition in which an edge strip of the foil projects beyond the profile member (10), while a face of the profile member is used as reference for the position of the cutting beam.
摘要:
A method for coating a preformed core having two faces and an edge around the periphery of the core, which edge links the two faces, includes thermoforming of a polymer material. The coating is formed by the heating, gluing and vacuum application of the two sheets of polymer material which are applied successively to the two faces of the core in order to cover same completely. An automatic machine can be used to carry out the method. The method can be used to produce finished products, in particular surfboards, furniture or display objects.
摘要:
The present invention relates to a laminating adhesive composition, which contains a reaction product which contains isocyanate groups and which is obtained from the reaction of at least two specific polyester polyols, solid at room temperature, and a polyisocyanate. Particularly in the case of three-dimensionally deformed support material surfaces, the laminating adhesive compositions permit removal from the laminating mold at an elevated temperature.
摘要:
A process for wrapping an edge flap of a workpiece having a covering sheet extending over a front face thereof and edge flaps protruding outwardly beyond the front face. The workpiece is positioned on a table, with one edge and the protruding flap overhanging and protruding outwardly beyond the table. The workpiece is disposed in proper location by positioning elements and clamps fix it to the table. adhesive is applied to the edge flap. A wrapping arrangement is provided with wiping blades so that upward movement of the wiping arrangement causes a first wiping blade to engage the edge flap and wipe it upwardly into engagement with an edge face, following which the wiping arrangement moves the second blade over the workpiece so that a second wiping blade engages the end part of the flap and wipes it downwardly into engagement with the back face of the workpiece.
