Abstract

See full text

Molding apparatus and method for molding of features integral with a base, such as in the production of fastener elements for hook-and-loop type touch fasteners, e.g. by the Fischer process, employs a mold roll formed of rings that have coolant passages formed within the ring components themselves for substantially direct contact with cooling liquid. Axial tie rods compress the mold rings together, contributing to the sealing of the coolant passages and the stiffness of the mold roll. Other types of sealing are disclosed. Mold cavities, including cavities used for injection molding, and cooling passages formed in either mold rings or injection mold plates by photo-chemical etching, laser machining and other techniques are disclosed. Various machines and methods taking unique advantage of these features are disclosed, including ring alignment methods.
