Shearing apparatus for cutting to length shrink materials, especially shrinkable plastic tubes, sealing members or the like

摘要

The invention relates to a shearing apparatus for cutting shrinkable plastic tubes to length, having a fixed blade holder for a lower blade and a movable blade holder for an upper blade. The two blade holders are arranged between two stationary bearing cheeks, the movable blade holder being mounted so as to be pivotable via a lever drive with respect to the fixed blade holder and a crank mechanism acting on the movable blade holder in such a way that the upper blade travels past the lower blade in the region of a slide-in window while executing a combined vertical and horizontal movement. In this manner, a transportable shearing apparatus is implemented which permits clean and even separating cuts on the building site, so that there is no longer a danger of damage to the shrink material during the shrinking process due to longitudinal cracks or the like.
