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.

A processing apparatus is disclosed comprising a shearing unit that receives the material to be processed from a conveying device upstream and surrenders it to a conveying device downstream, in which the material to be sheared advances with a continuous supply motion, in which each conveying device comprises a variable geometry closed loop slidable flexible element, in which the shearing unit is constrained to move with alternating motion together with two movable portions of the two conveying devices. The apparatus can process web-shaped material for the production of electrical energy storage devices.

A travelling planetary cutter (10), comprising: a cutting head assembly (11) comprising a rotating cutting assembly (30) comprising a blade guide block (32) carrying a cutting blade (34), wherein the blade guide block (32) is disposed for axial movement on a cutting block (33) so that cutting blade (34) may be moved towards and away from bearings (36) disposed on the cutting block (33); a blade cam block (42) also comprising part of the rotating cutting assembly (30) and itself comprising a blade cam (44) defining a cam surface (45), wherein axial movement of blade cam (44) of blade cam block (42) in direction (43) forces cam surface (45) to act upon a bearing (46) on blade guide block (32) to cause blade guide block (32) to move towards a workpiece to be cut (14) until cutting blade (34) engages workpiece (14) against bearings (36) while cutting blade (34) is rotated as part of rotating cutting assembly (30) to cut workpiece (14) wherein a speed of rotation of cutting blade (34) is maintained constant even while a diameter of workpiece (14) being cut decreases.

Method and device for guiding a tool in a recurring application of a product moved along an X-axis, wherein the tool is mounted on the Z-carriage of a cross guide and is moved therewith along the Z-axis standing perpendicular on the X-axis, wherein the Z-carriage is mounted on the X-carriage of the cross guide, the guide of which is mounted along the X-axis in a base plane, wherein the X-carriage is driven with an X-drive, wherein the Z-carriage is driven by a Z-drive, which is held stationary in the base plane and has a traction means driven by a first servo motor provided for the drive of the Z-carriage, which is driven from the base plane on the movable Z-carriage, wherein a movement of the Z-carriage that is brought about by the movement of the X-carriage and a motive force caused thereby on the traction means, is compensated when actuating the first servo motor provided for the drive of the Z-carriage.

An apparatus is provided for shearing a metallic belt from which electrodes of electric accumulators are formed. The apparatus includes a cutting device able to shear a metallic belt advancing along a sliding path, a first slider positioned upstream of the cutting device and a second slider positioned downstream of the cutting device. A handling system drives the first slider and the second slider cyclically with corresponding outward and return strokes, in order to change the length of the sliding path in such a way as to stop cyclically successive portions of the metallic belt at the cutting device, maintaining constant the advancement velocity of the metallic belt upstream and downstream of the cutting device.
