摘要:
A method and device for manufacturing of electrical components (15) on a continuous web (10) or discrete sheets of dielectric material (3), including the step to feed, from a supply roll (4) of a laminated web (1) or a supply of sheets consisting of at least one unbroken layer (2) of conducting material laminated on a flexible backing layer (3) of dielectrical material, said laminated web (1) or discrete sheets to a nip (6) between a patterned cylinder (7) and a cooperating cylinder (8) to shape said conducting layer into a repeated pattern of conducting material having ridges (13) and valleys (14), and the step to remove by mechanical machining conducting material from said thus shaped conducting layer. The step to remove conducting material from said conducting layer (2) is performed simultaneously with the step to shape the conducting layer (2) and by means of said cooperating cylinder designed as a milling cutter cylinder (8).
摘要:
Devices (34) and methods for inflating and sealing packaging pillows (28) from a material web (10) are shown for consistently producing high-quality packaging pillows.(28). A web of material (10) is advanced past an inflation nozzle.(40), inflated with gas, and sealed closed by a sealing element (66). The temperature of the sealing element (66) is monitored using a thermocouple connection and automatically adjusted using a closed-loop system. A sealing clamp parallel to the sealing element maintains two sheets of the web in contact through the sealing step. The inflation nozzle (40) is provided with two inflation outlets (42, 44), a first outlet (42) inserting gas longitudinally into the web of material, and a second outlet (44) inserting gas laterally into the material. Gas input is controlled with the use of relief valves to maintain pillow quality at all stages of production.
摘要:
A method to produce a perforated web material, wherein the web material (N) is fed through a nip (11) between a first roller (7) and a second roller (9) rotating in opposite directions and pressed against each other, the first roller (7) being provided with protuberances (7P) for perforation. Characteristically, the web material is heated before being fed into said nip.
摘要:
The present invention provides a method and apparatus for making a laminate. The method includes providing a work material such as a hide (14), and a backing material (38) and moving the two into engagement with one another and adhesively bonding the two. The apparatus includes a first support surface (16) for carrying a work material (14), a second support surface (28) positioned adjacent the first support surface (16), and means for transferring the work material between the two surfaces. A roll of backing material (36) is rotatably and operably positioned relative to two surfaces (16, 28) so that during movement of the work material (14) between the two surfaces (16, 28) the backing material (38) can be fed into engagement with a surface of the work material (14).

The invention relates to a wood-gluing system 10 enabling the continuous production of glued pieces of lumber 8, 9, 12 for panels and the like. The system includes a deck 11, a horizontal displacement system for advancing lumber across the deck, a braking system 14, a one-way clamping system and an upstream pressure system 30. The system may be used in conjunction with finger-jointing processes or with single pieces of lumber and may be used for the production of both furniture grade and construction grade wood products to NLGA and NGRC standards.
摘要:
A method for making a laminate adapted for decorating a substrate including providing (1) a sheet of pre-mask material including a cover layer and a layer of removable adhesive on one surface of the cover layer having an exposed surface defining a first major surface for the sheet of pre-mask material; (2) a supply length of decorative film tape comprising a length of decorative film having opposite first and second major surfaces, and a layer of adhesive along its second major surface; (3) a sheet of release liner having a first major surface adapted to be releasably adhered to by the removable adhesive on the cover layer and by the adhesive on the decorative film; and (4) a tape applicator. One of the sheets is supported with its first major surface in an application plane, and the tape applicator is used to form display lengths of decorative film tape of different predetermined shapes and lengths from the supply length of decorative film tape and to apply those display lengths of decorative film tape to the first major surface of that one of the sheets in a predetermined pattern; after which the first major surface of the other of the sheets is positioned over the surfaces of the display lengths of decorative film tape opposite the first major surface of that one of the sheets. The method adheres the layers of adhesive on the display lengths of decorative film tape to the to the release liner, and adheres the layer of removable adhesive included in the layer of pre-mask material over the first major surfaces of the lengths of decorative film in the display lengths of decorative film tape adhered to the release liner and to the release liner around the display lengths of decorative film tape.
摘要:
A substrate processing apparatus (10) includes a frame (14), first and second supply rolls (16, 18) and a substrate processing assembly including a resiliently deformable structure configured to apply pressure to the first and second supply rolls to perform a substrate processing operation. A method for processing a substrate (12) includes providing first and second supply rolls rotatably mounted to the substrate processing apparatus (10), wherein at least one of the first and second supply rolls has pressure-sensitive adhesive provided thereon. The selected substrate (12) is enabled to be fed in a substrate receiving opening with the first and the second substrates positioned on opposing sides thereof. The first and second substrates are advanced through the substrate receiving opening. A resiliently deformable structure deforms to apply pressure to the selected substrate and the first and second substrates as they are advanced through the substrate receiving opening, thereby bonding the adhesive to selected substrate
摘要:
A method for simultaneously sealing and creating a thermal perforation (107) between two thermoplastic layers (102). Drum (130) is provided and has at least one sealbar and perforation assembly (132, 134, 136, 138). Layers (102) are contacted to the assembly and are sealed with two generally opposing parallel seals (105). Perforation (107) is simultaneously created in layers (102) generally parallel to seals (105). Perforation (107) is located between seals (105).
