Abstract
The device for cutting individual tubes from a continuous tubular product moving in translation in an uninterrupted manner and formed by a production machine, comprises at least one frame that is stationary relative to the machine, an assembly that is movable in translation relative to the frame and supports a cutting head moved in reciprocating linear translation and in rotation, a first mechanism for moving said cutting head in reciprocating translation, a second mechanism for rotating said cutting head and a third mechanism for actuating the start and the end of the cutting operation, in which said mechanisms are stationary relative to the frame of the device.
Claims14
A device for cutting individual tubes from a continuous tubular product in uninterrupted translational movement and formed by a production machine, the device comprising:
- a chassis that is fixed relative to the machine,
- an assembly that is translationally mobile with respect to the chassis and supports a cutting head driven in reciprocating linear translational movement and in rotational movement, the cutting head including a cutting blade mounted on a rocker arm,
- a first mechanism including a first motor for driving the reciprocating translational movement of the cutting head,
- a second mechanism including a second motor for driving the rotational movement of said cutting head,
- a third mechanism including a third motor for actuating a start and an end of a cutting operation with the cutting blade, and
- wherein the first and second mechanisms are fixed in a direction of travel of the tubular product with respect to the chassis.
