Title: Method of shearing, punching sheet metal - uses vibration of tool in different sense to tool movement
IPC: B26D7/08
Filed: 1974-03-08
Abstract: The purpose of the vibrations is to impart a micromovement in a direction which is different to that of the plane of working on the tool. Vibrations are generated on the working stroke of the cycle and is done by suitably fixing a vibration generator onto the blade or punch. In the case of a vertical upstroke, vibrations are imparted horizontally along the cutting axis. If down sroking is used, the vibration may be in the ultrasonic range using horizontal waves. Punches do not require any particular orientation of the waves, but are applied perpendicular to the cutting axis.

Title: Dobby blade and hook stop system - has a cam drive for the parallelograms formed by the upper and lower blades
IPC: D03C1/06
Filed: 1974-08-30
Abstract: The design of a roller unit, for a dobby blade and hook stop, has a cam drive system with an outer cam path forming the basic circular path and a further path ranging outwards in a convex pattern on the outer side of each cam disc.
