Abstract
Abstract A machine is disclosed for applying a slider and an end stop in succession to a slide fastener chain on one and the same unit of the machine. The provision of a removably connected unit on the anvil part of the machine permits of the mounting of a slider and a bottom end stop as required on the fastener chain which has previously been attached to a prefinished garment such as trousers. The combination slider retainer and end stop die unit extends horizontally and forwardly of the anvil a sufficient length to provide unobstructed working space such that the fastener-attached, rather bulky garment can be advanced into the required position for the part assembly.
