Abstract:
A core adapter (100) for a core of a roll of sheet material allows the inside diameter of the core to be reduced. The core adapter is constructed of two or more concentric fiberboard tubes with a thermoplastic or thermosetting adhesive filling an annulus between the tubes.
Abstract:
The invention starts from a fastening element for attaching to a wall having a contact element having an adhesive surface (21) and a filling opening (18) via which a flowable adhesive agent can be brought between the adhesive surface (21) and the wall. Positioning elements (23a, 23b, 23c, 23d) by means of which the contact element can be positioned at the wall are arranged at the adhesive surface (21). To allow a good adhesion to the wall, it is proposed in accordance with the invention that the positioning element (23a, 23b, 23c, 23d) has a width which is variable in dependence on a spacing from the outlet opening (18). The width reduces at least sectionally as the spacing from the outlet opening (18) increases and is minimal at a maximum spacing (29) from the outlet opening (18). It is thus achieved that the adhesive surface can flow very easily around the positioning element (23a, 23b, 23c, 23d) on the introduction between the wall and the adhesive surface (21).
Abstract:
The invention relates to a method for gluing two disc elements (10, 12) together, in particular substrates for digital audio, video or data discs, such as Digital Versatile Discs (DVDs). The disc elements (10, 12) are held essentially horizontally and coaxially with one another so that a gap is formed between the disc elements, after which, in an inner area of the gap, a liquid adhesive is applied in the form of separate strands in the circumferential direction on the facing sides of the disc elements. The disc elements are brought together against one another and made to rotate rapidly in conjunction with the bringing together in order, by means of the gravitational force of the upper disc element and the capillary force of the adhesive, in association with the centrifugal force on the latter during the rapid rotation, to form a homogeneous and bubble-free adhesive layer of predetermined thickness between the disc elements.
Abstract:
The invention relates to a method and a device for glueing together two disc elements (12, 14). The two disc elements are brought together coaxially against each other to form a gap (46) between the disc elements. In an inner area of the gap (46) a liquid adhesive is applied so that it comes essentially simultaneously into contact with facing sides of the two disc elements (12, 14). The disc elements are then brought towards each other to achieve a uniform adhesive layer between the disc elements. The device comprises lower and upper holders (30, 32) for respective disc elements, and a means (54) applying a liquid adhesive in an inner area of the gap (46).

Abstract:
A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity, The cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid porting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may he imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.
