Abstract: A cassette (10a, 10b, 11), which contains juxtaposed wire staple blanks releasably interconnected to form at least one strip (8) of staple blanks, is adapted to be used in a stapler for driving staples into an object, such as a sheaf of papers. The stapler comprises a base and a stapler head movable in relation to the base. The cassette accommodates a reciprocating staple shaper (20), adapted to successively shape the staple blanks of the strip (8) into U-shaped staples, and a reciprocating staple driver (19), adapted to successively release the thus-formed staples from the strip (8) and drive them into an object. The cassette has a front wall (11) in which the staple shaper (20) and the staple driver (19) are displaceably guided, as well as recesses through which projections on the staple shaper and the staple driver project, so as to engage, when the cassette is mounted in the stapler head, a drive mechanism (4) arranged in the stapler head to reciprocate the staple shaper and the staple driver.

Abstract: A stapler comprises a stapler head which accommodates a strip of wire staple blanks and is pivotable between a starting position and a working position, in which it is applied against a sheaf of papers. A staple shaper shapes the blanks into substantially U-shaped staples, and a staple driver releases the thus-formed staples from the strip and drives them one by one into the sheaf of papers. A pivotable operating device reciprocates the staple shaper and the staple driver. A drive device is adapted to pivot the operating device in such a manner that it causes the staple driver to drive a staple into the sheaf of papers in a driving stroke and causes the staple shaper to shape the following staple in a shaping stroke, as well as adapted to pivot the stapler head to its working position before the staple driver performs the driving stroke and retain it there during the driving stroke of the staple driver.

Abstract: A stapler for driving staples (5) into an object (6) has a frame (1), a magazine (2) arranged in the frame and containing staples (5), and a drive element (3) adapted to push staples (5) out of the magazine (2) and drive them into the object (6) and, to this end, be reciprocated by means of a drive mechanism. The drive mechanism consists of a drive cylinder (19) rotatably mounted in the frame (1) and having an endless groove (23) in its circumferential surface. The groove (23) extends substantially helically from a starting point to a turning point axially spaced therefrom, and thence substantially helically back to the starting point. The groove (23) accommodates a groove follower (24) connected to the drive element (3) in order, upon rotation of the drive cylinder (19), to reciprocate the drive element (3).

Abstract: A stapler for driving staples (2) into an object (3) has a drive element (1) for pushing a U-shaped staple (2) out of a magazine (10) to drive its legs (2a) through the object. The stapler also has an anvil device (11) comprising two anvil members (4) which are substantially symmetrically arranged with respect to the staple (2) driven into the object, and which are each pivotable about an axis (5) substantially perpendicular to the plane of the staple, the anvil members (4) being pivotable between a starting position, in which they are so positioned that the free leg ends of the staple (2) will engage the respective anvil member when the staple is driven into the object, and an end position, in order, when pivoting from the starting position to the end position, to bend the projecting end portions of the staple legs (2a) driven through the object (3), against the object in a direction towards each other.

Abstract: A stapler for driving staples into a sheaf of papers comprising a base, a stapler head pivotably connected to the base via a first pin and pivotable between a starting position and a working position in which it is applied against a sheaf of papers placed between the base and the stapler head. A reciprocating drive element, adapted to drive a staple into the sheaf of papers during a driving stroke, is arranged in the stapler head. An operating mechanism, adapted to drive the drive element, is pivotably connected to the stapler head via a second pin parallel to the first pin. A drive mechanism is arranged in the base for pivoting the stapler head and the operating mechanism. A locking mechanism is arranged in the stapler head for releasably locking the stapler head in a working position while a staple is being driven into the sheaf of papers.

Abstract: An electric tool for driving in fixing elements (10) into an object (4) by means of a magnetic field generated by supplying magnetizing current to an electromagnetic device, comprises a circuit means (17) which is adapted, when activated, to supply magnetizing current to said electromagnetic device. The tool comprises two actuators (18, 19) alternatively connectible to the circuit means (17) and adapted, when actuated, to activate the circuit means, one (18) of the actuators being an actuator which is activatable in a potential-free mode and which is, in an initial position, unconnected to the circuit means, and the other (19) of the actuators being connected to the circuit means in the initial position.

Abstract: A tool for fastening an elongated object on a supporting surface with U-shaped clips, each embracing the elongated object and being secured to the supporting surface by a fastening member extending through one of its legs. The tool comprises a magazine for receiving a succession of clips to be successively fed through the magazine, a feed device which is adapted to feed the succession of clips in a direction towards a determined mounting position at the front end of the tool, and a driving device with a driver for driving the fastening member of a clip in the mounting position into the supporting surface. The magazine is designed to receive the clips with their fastening members in such an orientation that each clip has its U-legs disposed after each other in the longitudinal direction of the magazine so that it may be secured over the elongated object oriented transversely of the longitudinal direction of the magazine.
