Material strip repetitive stamping or separation device - uses driver first faster than material flow speed, then synchronising with it

摘要

Installation for the repetitive stamping or separation of strips of material in profile machines, in which the working and cutting lengths are adjustable by means of a repeater selector, uses a separating slide with a saw operated by a material driver. The driver takes the form of an adjustable and displaceable stop, and is acted upon by damping cylinder which tends to slow it down, and which, after the machining process, acts as return cylinder. The driver(1), by switching on an accelerator drive cylinder(5), exceeds the throughflow speed of the material(7) to be worked, and then, by means of the damping cylinder (10), is brought back to the same speed as the material running through the machine.
