<p>The trapezium shaped knife blade has a number of holes (8, 10) and notches (7, 9) with which it can be located in a slide piece (6). The knife blade is symmetrical and can be reversed when one side has worn out. The slide piece is made from elastomer or plastic. Two spring legs (15, 16) are integral with the slide and clamp the side in the housing. One of the spring legs can be pushed down by pressing on a button (12). This allows the slide to be moved in the housing. The housing is made in two halves as e.g. a die casting which are clamped together by a screw.</p> |
