A method for producing a partly transparent body with a color gradient, include: providing a transparent first casing having a first joint surface on a protrusion and including an encased object; providing a second casing which is not completely transparent and which has a second joint surface in a recess. The shape of the protrusion and the shape of the recess correspond to each other; and combining the first casing and the second casing by inserting the protrusion into the recess and melting the first joint surface of the first casing with the second joint surface of the second casing. A pressure force and a temperature are applied to the first joint surface and the second joint surface such that the first joint surface of the first casing transitions into the second joint surface of the second casing in a visually seamless manner, followed by a removal of material.

A splice is described for jointing thermoplastic strips that include steel cords. In the splice a splice polymer is used that is a mixture of a co-polymer and a base polymer, wherein the co-polymer is a grafted co-polymer, a block co-polymer or a random co-polymer functionalized for enabling adhesion to the steel cords. Particular about the inventive splice is that the amount of co-polymer in the base polymer is such that in a test-till-break of a splice, part of the steel cords fracture in the test while the remaining cords are pulled out of the polymer without breaking. Surprisingly, a splice with such a failure behavior results in a better overall splice strength than a splice wherein a too large amount of co-polymer is added. When too much co-polymer is added all steel cords break in the test which strangely enough leads to a lower overall strength of the splice.

A method of splicing together a first composite core and a second composite core can include: positioning a first flange of the first composite core adjacent to a second flange of the second composite core, applying an adhesive, and locating a first magnet and a second magnet to provide a pressure on the adhesive.

A method of carving a contour surface on a composite core can include positioning a first edge of the composite core against a first tooled member; locating a first magnet within an outer cell member along the first edge of the composite core so that the first edge of the composite core is magnetically drawn to the first tooled member; locating a second magnet along a second edge of the composite core such that the second edge of the composite core is magnetically drawn to a second tooled member; and carving a first contour of the composite core.

摘要:
A plain stepped splice lay-out scheme is presented that can be used for splicing strips to one another that comprise longitudinally arranged cords. The strips can take the form of a conveyor belt, transmission belt, timing belt, elevator belt, a rubber track or a reinforcing strip. The splice is optimised for uniform bending stiffness and maximum strength retention. The cross section of the strip and the splice are substantially equal: there is no increase in thickness or width at the splice. The splice lay-out is characterised by the fact that the abutments (130)—those positions where cord ends (111, 121) meet—are positioned sufficiently far away from one another and by preference as far away from one another as possible. Preferred embodiments in terms of length common between cords of the different strips and local strength are given.
