Abstract
Arrangement for securing a replaceable cutting blade (1) on a rotating knife holder (2) in a cutting assembly for a meat mincing machine, the blade (1) of the rotating knife holder (2) rotating along the surface of a perforated disc (3), the arrangement comprising at least one slot (4) in the knife holder (2) adapted to the thickness of the cutting blade (1) in such a way that the replaceable cutting blade (1) can be positioned in the slot (4) and thereby partially secured in the knife holder (2). The arrangement comprises a screw (5) positioned in a threaded bore (6) provided in the knife holder (2), the threaded bore extending transversely with respect to the slot (4) in such a way that the screw (5) can be moved in the threaded bore (2) to engagement with a replaceable cutting blade (1) inserted into the slot for completely securing the blade in the knife holder (2). The threaded bore (6) is provided as a blind hole with a minor hole at the bottom for insertion of a tool for tightening the screw (5). By this arrangement it is achieved that the screw (5) is prevented from falling out of the arrangement and into the product.
