    摘要： A cutting unit according to the invention comprises a stationary frame (1), a cutting drum (5) having a cutting knife (7) on an outer cylindrical surface thereof and a central axis, and an anvil drum (6) having an outer cylindrical surface and a central axis. The cutting drum (5) and the anvil drum (6) are arranged one over the other with parallel centre axes for cutting web material fed between them. The upper of the cutting drum (5) and the anvil drum (6) is centred on an arbour, which is rotatable supported in the stationary frame and connectable to a driving device for rotating the arbour and the upper drum around the centre axis thereof. The lower of the cutting drum and the anvil drum is arranged rotatable around the centre axis thereof, and is arranged movable towards and away from the upper drum. The cutting unit further comprises a carrier (16), which is arranged movable towards and away from the upper drum. The carrier (16) comprises at least two contact rollers (19), which have an outer cylindrical surface and which are arranged rotatable round a respective axis in the carrier, which axes are parallel to the centre axis of the cutting drum (5) and the anvil drum (6). The lower drum is shaftless and is arranged with the outer cylindrical surface thereof resting on the outer cylindrical surface of the at least two contact rollers (19), wherein at least one contact roller (19) is situated on either side of a central vertical plane of the lower drum for providing vertical and transversal support of the lower drum by the contact rollers only. The carrier (16) is connectable to a pressing device for moving and pressing the carrier (16) and the lower drum carried thereby towards and against the upper drum for providing cutting pressure between the upper drum and the lower drum.

    摘要： The invention relates to an apparatus for cutting metal strip comprising first and second rotatable drums (6, 7) with corresponding first and second cutting means arranged side-by-side so that the metal strip may pass between them, the first and second cutting blade means (8, 9) is retractable between a first retracted position in which the strip is permitted to pass freely between the drums (6, 7) whilst they are rotating and a second extended position in which the blade means (8, 9) extends ourwardly from the drum (6, 7) to cut the strip. The first and second drums (6, 7) are provided with an actuator rod (21, 22) arranged axially in the drum such that axial movement of the actuator rod (21, 22) results in corresponding extension or retraction of the cutting blade means. The first cutting blade means may be fixed and the second cutting blade means is retractable or alternatively both may be retractable. Axial movement of the actuating rod (21, 22) causes extension followed by retraction of the blade in a single movement of the actuating rod (21, 22) by means of an external surface which undulates along its length.

    摘要： Upper and lower rotating drums (13, 14) having shearing blades (13a, 14a) are supported by a bearing frame (12) via eccentric sleeves (15, 16). Only the upper rotating drum (13) can be rotated by a drive motor 17, while the eccentric sleeves (15, 16) are rotated by a drive motor 25, so that the rotating drums (13, 14) can be made to approach and separate from each other. Interlocking gears (29, 30) are fixed to shaft end portions of the rotating drums (13, 14) to permit interlocking of the rotating drums (13, 14) when these drums approach. Oldham's couplings (41, 42) are interposed between the interlocking gears (29, 30) and timing gears (33, 34) to rotate the rotating drums (13, 14) constantly synchronously.
