Technological purpose:
For cutting sheets and strips of sheet metal according to pre-punching or using a stop.
Construction design:
Manual, lever-operated, with progressive cutting. The stand with a wide table and the cutting lever are made of gray cast iron. The cutting lever, rotatably mounted on a pin fixed in the table, is balanced
with a counterweight. For repeated cutting of strips of the same width, the shears are equipped with a front stop, which is adjusted using a toothed rack and pinion. The pinion is rotated
by a hand wheel; the set position is secured with a locking lever. Diagonal cuts can be made by adjusting the auxiliary ruler in the table or by angularly rotating the front stop.
For cutting narrower strips, the stop is equipped with spring-loaded supports. The necessary values for parallel and diagonal cuts can be read from the corresponding scales.
During cutting, the sheet is held in place by a hold-down operated by a lever with an eccentric.
Shears of similar construction are the NTP 1000/2-J.
