Steel strip drilling, cutting and notching device for fabricating sealing joint in e.g. building industry, has series of hobs and drive pinion wheel formed as single unit, where strip continuously passes between wheel and hobs
The device has a series of hobs (4) and a drive pinion wheel (1) formed as a single unit, where a steel strip continuously passes between the wheel and the hobs and is driven on entire length of an anvil (11) that serves as a cam. The wheel is rotated around an axle. The hobs with rolling bearings are integrated in pairs by links (9). Pinions (5) are distributed on entire circumference of the wheel. The anvil is fixed in a fixed wheel (2) to permit movement of penetration of the pinions.
