FILAMENT CUTOFF AND HOLDING HEAD

摘要

In a rod-wrapping machine moving a filament supply about a rod to be wrapped, an improved filament cutoff and holding head is provided with an L-shaped slidably mounted grab which is moved by a double acting air cylinder to extend under a final turn of the wrapping and then be retracted to cutoff the filament against a knife edge and clamp the filament adjacent to the knife edge. The head has a filament positioner which pushes the clamped filament away from the head at the start of a winding cycle. A diaphragm overrides the double acting cylinder to slightly move the grab and release the filament.
