摘要:
A laminator for use in attaching a film (4) cut to a predetermined length to a substrate (1) having positioning holes (guide holes). A boring unit (30) for making holes (through holes of a predetermined size in the portions of the film (4) which correspond to the positioning holes in the substrate (1) is provided in a predetermined position in a film feed path along which the film (4) is supplied from a film feeder to the upper surface of the substrate (1). Owing to this arrangement, the present invention enables holes to be made in the portions of the film (4) which correspond to the positions of the positioning holes in the substrate (1), before the film (4) has been attached to the substrate (1) or while the film (4) is attached to the substrate (1). Accordingly, the operation efficiency can be improved. The laminator is further provided with a device for removing chips of the film (4), which occur when the holes are made in the film (4) with the boring unit (30). Owing to this device, the holes can be formed in the mentioned portions of the film (4) with the chips thereof removed at the same time, before the film (4) has been attached to the substrate (1) or while the film (4) is attached to the substrate (1). Therefore, the yield of the laminated products can be improved.
摘要:
A method and a device for melt-cutting a label by blowing hot air against the label made of a heat-shrinkable tubing adhered closely to the periphery of a bottle or the like. Spray nozzles for flowing hot air are composed of a plurality of blocks which are easily adjustable forward and backward. When the cylindrical part of the bottle is of a curved shape, by adjusting said blocks individually the distance between each block and the curved surface of the bottle can be adjusted to a predetermined interval.

Apparatus for forming a tube, preferably of flexible thermally insulating material, comprises a cutting head (14) with a pair of concentric cutting edges (16,18) which cooperates with a presser head (28) to cut rings (50) of material from a sheet (48) presented to the cutting head (14). The rings (50) are stacked up on a guide bar (32) and sprayed with a coating composition to consolidate them into a tube (54) which may be collected on a take-up drum in a continuous manner.

A water activatable sheet (1) containing a paper material having on at least one surface thereof a porous water absorbing layer (3) that has a liquid absorption volume of from 1 to 10 mL/m 2 , further having provided on the water absorbing layer an adhesive layer (4) containing an aqueous adhesive coated and solidified by drying solves the problems of ordinary glue label, i.e., the wrinkles of a label and the effusion of an adhesive due to dew condensation, the labor on applying the label, and the adhesive deposits on an adherend and the contamination of cleaning water on stripping off the label.
摘要:
An apparatus for sealing a substrate assembly by applying a force to the assembly while simultaneously exposing the substrate assembly, and in particular a sealing material disposed between two substrates of the substrate assembly, to an irradiating beam of electromagnetic energy. The beam heats, cures and/or melts the sealing material, depending upon the sealing material to form the seal. The force is applied by directing a flow of fluid against the substrate assembly, and beneficially improves contact between the substrates of the substrate assembly and the sealing material during the sealing process, therefore assisting in achieving a hermetic seal between the substrates.
摘要:
An apparatus and device for fusing two or more foam components together by thermal welding, the apparatus and device comprising an interface blade adapted for placement at an interface of foam components to be fused together, and a nozzle proximate to the interface blade for distributing a heated gas at the interface of the foam components. The nozzle may be located in a shroud proximate to the interface blade. An automated foam welding apparatus has a platform for supporting foam components or other components, a clamp for applying pressure to one or more of the foam components, and one or more welding heads mounted upon a track for translation proximate to the foam components to be welded together, the welding heads having an interface blade and a heated gas distribution nozzle, and optionally a trimmer for trimming excess material from one or more of the foam components. A hand-held foam welding device is also described.
摘要:
To apply a resin impregnated fabric to a substrate, a pressure shoe module (36) includes a surface having a conforming layer of material (46) and a curved forward edge (50) . A contact surface (44) moves relative to the substrate and to conform to the substrate. The conforming layer of material is compatible for use with the resin. The curved forward edge is disposed at the front of the surface relative to the movement of the device to the fabric and is curved with a center portion of the curved forward edge being relatively forward of a pair of side portions of the curved forward edge. An automated fabric lamination machine (AFLM) includes a positioning device (12) to control the movement of an end effector (14) relative to a layup mold or tool (16). The positioning device (12) includes any suitable system to control the movement of the end effector (14) relative to the tool (16).
摘要:
The invention refers to a process for manufacturing a headliner for the interior of an automobile and comprises the steps of:
introducing at least one layer intended for constituting a support and one lining layer (200) in a press (300); applying pressure and heat on the layers and thus obtaining an assembly of layers joined to one another; cutting the support (100) such that a surplus portion (102) of the support is separated from a main portion (101) of the support; applying a hot fluid on the lining layer in the area in which it is adhered to the surplus portion of the support; separating the surplus portion (102) of the support from the lining layer (200); covering a trimmed edge (101 a) with the lining layer (200).
The invention also refers to a machine or installation useful in this type of process.
