Abstract:
La présente invention concerne un procédé d'adhésivage d'un lé de revêtement de sol (1) en continu permettant d'obtenir un revêtement de sol (1) auto-adhésif revêtu d'un film de colle (2) sur toute sa largeur sans bavure de colle sur les tranches longitudinales du lé de revêtement auto-adhésif (1). Pour ce faire, le procédé consiste à contre-coller sur la face inférieure d'un lé de revêtement (1) défilant en continu, un ruban adhésif de transfert (7) comprenant un film de colle (2) destiné à être fixé sur la face inférieure (3) du lé de revêtement (1) et un support protecteur (8) non adhésif, la largeur du ruban adhésif de transfert (7) étant supérieure à la largeur du lé de revêtement (1), de manière à ce que le film de colle (2) et son support protecteur (8) débordent de chaque côté du lé de revêtement (1); à neutraliser les deux bordures (9,10) du film de colle (2) de chaque côté du lé de revêtement (1), en les prenant chacune en sandwich entre le rebord longitudinal (17, 18) du support protecteur (8) du ruban adhésif de transfert (7) et des moyens de neutralisation (iii.1, iii.2) en contact avec les bordures (9,10) et venant à ras de la tranche (5,6) du revêtement (1); à retirer ensuite le support protecteur (8) du ruban adhésif de transfert (7), de façon à obtenir une rupture nette du film de colle (2) le long des deux bords longitudinaux du lé de revêtement (1); et à contre-coller sur le film de colle (2) un film protecteur (19) de largeur supérieure au lé de revêtement (1). L'invention concerne également un dispositif pour la mise en œuvre de ce procédé.
Abstract:
Engineered composite coated flat-rolled steel strip is produced in continuous line operations, in which flat-rolled steel strip, free of surface iron oxide, having a metallic corrosion-protective coating, is polymer coated in continuous-line operations in which a plurality of adherent thin-film layers of polymeric material are deposited on a strip surface. In a dual-surface polymeric coating embodiment, each surface is separately-pretreated for surface adhesion, solidified, and polymeric overhang is removed. Finish processing re-melts the polymer coating and rapidly cools that coating through glass-transition temperature to establish amorphous characteristics in the polymeric coating materials. An anhydride-modified polypropylene, first contacts the strip, an intermediate layer can include about fifteen to twenty five percent, by weight, polybutylene with the balance polypropylene; an outer surface polymeric layer includes about five to ten percent, by weight, polybutylene with the balance polypropylene.
Abstract:
Floorboards are shown, which consist of a core and a surface layer and are provided with decorative joint edges which are formed by removing the surface layer.
Abstract:
A laminated composite material (2) is provided. The material has first and second layers. The first layer is composed of a fibrous material (6) and a binder, and the second layer is composed of a woven material (8) and a binder.
Abstract:
A device for separating layers of laminate trim includes a pair of nip rollers (22) defining a feed path for a laminate, at least two winders (16, 18) and a drive system (54, 56) for the winders. The winders are preferably arranged on an upstream side of the nip rollers. The device can be provided at the output of a lamination machine to receive longitudinal trim portions cut from a laminate (50) being formed by the lamination machine (46), so as to provide continuous delamination of trim exiting the lamination machine. In the case of a three (or multiple) layer laminate, the device can include a third winder (20) (or additional winders) for collecting a middle layer of the laminate.
Abstract:
A laminate such as a PCB material is formed by stacking resin impregnated prepreg sheets (10) between copper foils (12), applying heat and pressure around the periphery of the stack to form an edge-sealed unit, and subjecting a number of such units to a lay-up process in a separate clean area into which they are introduced via surface-cleaning means.
Abstract:
A method of processing a flexible glass sheet having a thickness of equal to or less than 300 µm includes separating an outer edge portion of the flexible glass sheet from a bonded portion of the flexible glass sheet along a separation path while the bonded portion of the flexible glass sheet remains bonded with respect to a first major surface of a carrier substrate. The step of separating the outer edge portion provides the flexible glass sheet with a new outer edge extending along the separation path. A lateral distance between the new outer edge of the flexible glass sheet and an outer periphery of the first major surface of the carrier substrate is equal to or less than about 750 µm.
Abstract:
Systems and methods for utilizing a trimming device to trim an edge of a plastic card having round corners, are provided. The plastic card has an overlay laminated on a major surface of the plastic card. The periphery of the overlay overhangs the edge of the plastic card. The trimming device trims the overhanging part of the laminated overlay by moving the trimming device along the edge of the personalized document in a direction generally parallel to the major surface of the plastic card.
Abstract:
The present invention relates to laminate of films for applications in which relatively high yield strength and ultimate tensile strength is required. In one embodiment this is accomplished by drawing tube (106) from a storage means onto a tube roller and cutting the tube length into two film, a first film and a second film, where the first and second film are in opposite angular direction with respect to the roller rotation, coating the first film with liquid adhesive composition by passing between at least two film guiders, where one of the guider is dipped in liquid adhesive tray (110), in which said composition includes resin and hardener and laminating the second film with the coated liquid adhesive first film by passing them together through at least two film guiders (112) under pressure to produce a spiral cut liquid adhesive laminated film.
