Abstract

A device for rotary conversion of a web or sheet material by cooperating cylindrical tools. The tools are arranged in a cassette. A driving device connects with the tools for rotating them. The cassette with the tools is placed in an adaptive cassette receiver. The driving device includes a motor and is supported on the lid of the cassette receiver. The cassette is placeable in and removable from the cassette receiver and is secured there and the driving device is connected to the tools.

Claims

1. A device for rotary conversion of a web or sheet material in a processing machine, wherein the device comprises:

a tool cassette comprising a supporting first frame, a pair of cooperating cylindrical tools supported in the first frame and the cylindrical tools being operable to convert the web or sheet material;

an adaptive cassette receiver comprising a second frame configured for being removably received in an opening in said processing machine;

a driving device including a motor for rotating the cylindrical tools;

the first frame being removably disposed in the second frame and the cylindrical tools in the first frame being attached via the second frame to the driving device for rotating the cylindrical tools.

2. The device of claim 1, wherein the adaptive cassette receiver has an internal profile shaped to position and fix the tool cassette and the tool cassette has a profile for being received in the internal profile of the adaptive cassette receiver to fix the tool cassette in the adaptive cassette receiver;

the adaptive cassette receiver having an external profile to position and fix the adaptive cassette receiver in the processing machine.

3. The device of claim 2, wherein the driving device is disposed on the adaptive cassette receiver and in driving contact with the cylinders.

4. The device of claim 2, further comprising:

a positioning device in the adaptive cassette receiver for positioning the tool cassette against movement with respect to the adaptive cassette receiver and at a position for being engaged by the driving device, whereby the driving device may drive the tools.

5. The device of claim 4, wherein the driving device is disposed on the adaptive cassette receiver and is in driving contact with the cylinders.

6. The device of claim 2, wherein the adaptive cassette receiver comprises upstanding brackets spaced apart and being shaped to together define the internal profile for receiving the tool cassette;

the upstanding brackets having a bottom region below the tool cassette, a crossbeam joining the brackets at the bottom region;

a lid of the adaptive cassette receiver disposed over the tool cassette and the lid being attached to the tool brackets for holding the adaptive cassette in the cassette receiver.

7. The device of claim 6, further comprising a column on the lid of the adaptive cassette receiver and the driving device being moveable along the column for positioning with respect to the tool cassette.

8. The device of claim 7, wherein the tool cassette is engaged with the driving device by vertical displacement of the driving device along the column.

9. The device of claim 1, wherein the driving device is disposed on the adaptive cassette receiver and in driving contact with the cylinders.

10. Device for rotary conversion of a web or sheet material in at least one processing station arranged in a machine, comprising:

a tool cassette comprising a first frame holding a pair of cylindrical tools for being rotated by a driving device equipped with a motor;

said tool cassette being removably accommodated in an adaptive cassette receiver, said adaptive cassette receiver comprising a second frame and being configured for being removably received and held in an opening in said processing station;

said driving device being arranged on the adaptive cassette receiver and drivingly connected to said tools.

11. Device according to claim 10, wherein the adaptive cassette receiver has an internal profile designed so as to position and fix the tool cassette therein, and an external profile designed so as to position and fix the adaptive cassette receiver in the processing machine.

12. Device according to claim 11, wherein the adaptive cassette receiver is equipped with a positioning device for blocking the tool cassette in a position for allowing the driving device to drive the cylindrical tools.

13. Device according to claim 12, wherein the adaptive cassette receiver is formed by two pairs of brackets secured to a crossbeam fixed at their base and by a lid fixed at their upper end.

14. Device according to claim 13, wherein the driving device is vertically movable along a column fixed to the lid.

15. Device according to claim 14, wherein driving engagement with the cylindrical tools is achieved by vertical displacement of the driving device.
