Abstract:
A device for bonding a thermoplastic tape to a substrate to form a fully consolidated composite. This device has an endless chain associated with a frame so as to rotate in a plane that is perpendicular to a long dimension of the tape, the chain having pivotally connected chain links with each of the links carrying a flexible foot member that extends outwardly from the chain. A selected number of the foot members contact the tape, after the heating thereof, to cause the heated tape to bond to the substrate. The foot members are each a thin band of metal oriented transversely to the chain, with a flexibility and width and length to contact the tape so as to cause the tape to conform to the substrate to achieve consolidation of the tape and the substrate. A biased leaf-type spring within the frame bears against an inner surface of the chain to provide the compliant pressure necessary to bond the tape to the substrate. The chain is supported by sprockets on shafts rotatably supported in the frame and, in one embodiment, one of the shafts has a drive unit to produce rotation such that the foot members in contact with the tape move at the same speed as the tape. Cooling jets are positioned along the frame to cool the resultant consolidated composite.
Abstract:
A method for manufacturing an optical disc. The method includes the steps of peeling a release paper from a four layered adhesive sheet member, which is composed of an elongated release paper, a protective sheet attached to the release paper, an adhesive layer formed on the protective sheet, and a release paper formed on the adhesive layer. A three layered adhesive sheet member which results from the peeling of the release paper is applied to the single layered disc, the protective sheet is transferred and bonded to the surface of the single layered discs and the elongated release paper is peeled off from the protective sheet bonded to the single layered disc to expose the protective sheet on the upper side of the single layered disc.
Abstract:
A packaging machine comprises a chamber (4) having a cover (5), wherein the cover (5) which is liftable from a lowered position in which a chamber (4) is closed into a lifted position, in which a chamber (4) is opened. It is the object of the device or the method to improve the ergonomic accessibility and the visibility of the cover inside of a vacuum chamber of a packaging machine during maintenance, repair or cleaning work. For this purpose, the cover (5) is pivotable in the lifted position.
