Method and device for producing a chain
Abstract:
The invention relates to a method and device for producing a chain composed of chain links and of connecting elements. According to the invention, the chain can be produced in an essentially continuous manner whereby largely eliminating the need to make separating cuts and enabling the production of loadable and durable articulated connections of chain links. To this end, the invention provides that: connecting elements each having two holes are used; the connecting elements are inserted in cavities in first tools, and; chain links are produced with contact at least to partial areas of connecting elements. Inside the holes, joint pins are produced that are a part of the chain links. The invention also relates to a method and device for producing a chain, which is composed of chain links and of connecting elements, made of shapeable materials, particularly plastic.
