Abstract
Abstract A lightweight pistol-type synthetic yarn slicer employing radiant heat to fuse the synthetic yarn without direct contact between the yarn and heating element. The apparatus contains a first retarder for the trigger stroke causing the yarn ends to traverse the heating zone in a controlled manner and a second retarder unit causes delayed activation of an indicator which, in effect, times the exposure of the synthetic yarn to the radiant heat.
