Title:
スクラップシャーまたはこれに類するものに設けられた、閉鎖運動の途中で粉砕材料の作用を受けて出現する摩擦力を減少させるための装置
Document Type and Number:
Japanese Patent JP2005538843
Kind Code:
A
Abstract:
The invention relates to scrap shears ( 1 ) comprising several jaw arms ( 2 a, 2 b, 3 ), which can execute a pivoting motion in relation to one another in a closing or opening direction of the scrap shears. At least one jaw arm is equipped with a counter-bearing element ( 12 ) on the end section lying opposite the mounting ( 4 ), said element being displaced, (at least temporarily), in relation to the jaw arm carrying said element between a working position and a reduced friction position. The counter-bearing ( 12 ) is configured in such a way that the distance between its external surface ( 12 b), which faces away from the carrying jaw arm and the mating surface ( 3 b) of the neighbouring jaw arm ( 3 ), which faces towards said external surface, increases with the relative displacement of the counter-bearing element towards the reduced friction position.
