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.

Claims

1. A cutting device comprising a cutting blade secured to a rotatable holder, said rotatable holder including at least one slot that is configured and dimensioned to receive the cutting blade, and a threaded bore comprising at least two collinear sections arranged on either side of said slot;

and a screw operatively associated with the threaded bore to secure the cutting blade within the slot.

2. The cutting device of claim 1, wherein the screw has a conical tip and the cutting blade has a cut-out portion for engaging said conical tip to secure the cutting blade within the slot.

3. The cutting device of claim 2 wherein the threaded bore includes stopping means for preventing the screw from being screwed into said threaded bore to a point where the conical tip is unable to engage the cut-out portion.

4. The cutting device of claim 1, wherein the cutting blade rotates along the surface of a perforated disc.

5. The cutting device of claim 1, wherein the slot has a thickness which is about the same as that of the cutting blade.

6. The cutting device of claim 1, wherein the cutting blade has an insert slot for manually inserting and removing the cutting blade when the screw is loosened, but still protrudes into the slot.

7. A method for securing a cutting blade to a rotatable holder which comprises:

providing the cutting blade with a cut-out portion and the holder with at least one slot which is configured and dimensioned to receive the cutting blade and which includes a threaded bore said threaded bore comprising at least two collinear sections arranged on either side of said slot;

inserting a screw having a conical tip into the threaded bore to a point where the conical tip extends into the slot by a sufficient distance to engage the cut-out portion;

inserting the cutting blade into the slot; and

tightening said screw onto the cutting blade to secure the cutting blade in the slot.

8. A cutting device comprising a cutting blade with a cut-out portion secured to a rotatable holder, said rotatable holder including at least one slot that is configured and dimensioned to receive the cutting blade, and a threaded bore said threaded bore comprising at least two collinear sections arranged on either side of said slot, wherein the threaded bore includes stopping means for preventing the screw from being screwed into said threaded bore to a point where the conical tip is unable to engage the cut-out portion;

and a screw operatively associated with the threaded bore to secure the cutting blade within the slot, wherein the screw has a conical tip and the cutting blade has a cut-out portion for engaging said conical tip to secure the cutting blade within the slot.

9. A cutting device comprising a cutting blade secured to a rotatable holder, said rotatable holder including at least one slot that is configured and dimensioned to receive the cutting blade, and a threaded bore said threaded bore comprising at least two collinear sections arranged on either side of said slot, and a screw operatively associated with the threaded bore to secure the cutting blade within the slot, said threaded bore having a screw insertion end from which the screw is inserted into the threaded bore, and an opposite tool insertion end from which a tool is inserted to engage the screw, the bore including stopping means positioned between the slot and the tool insertion end for preventing the screw from being screwed into the threaded bore to a point where the screw exits the threaded bore at the tool insertion end.

10. The cutting device of claim 9, wherein the stopping means are positioned to prevent the screw from being screwed into the threaded bore to a point where the conical tip is unable to engage a cut-out portion of the cutting blade.

11. A cutting device comprising a cutting blade secured to a rotatable holder, said rotatable holder including at least one slot that is configured and dimensioned to receive the cutting blade, and a threaded bore comprising at least two collinear sections arranged on either side of said slot;

and a screw operatively associated with the threaded bore to secure the cutting blade within the slot, said screw having a conical tip and said cutting blade having a cut-out portion for engaging said conical tip to secure the cutting blade within the slot; and

said threaded bore having stopping means for preventing the screw from being screwed into said threaded bore to a point where the conical tip is unable to engage the cut-out portion.
