A strapping apparatus for strapping articles with a strapping band having a tensioning device for imparting a band tension to a loop of the strapping band, the tensioning device including a driveable tensioning element provided for engaging the strapping band to impart a band tension. The strapping apparatus including a connecting device for generating a permanent connection, in particular a welded connection, at two regions, situated one above the other, of the loop of the strapping band. The strapping apparatus is configured to achieve the release of the tensioning element from the strapping band reliably to avoid or reduce adverse characteristics attributed to the release of the tensioning device from the band.

A strapping device includes a handle, a body, and an actuator. The handle includes an input device and a switch, the input device spaced from the switch by a biasing element that applies a bias force to the input device. The input device moves from a first state spaced from the switch to a second state contacting the switch responsive to receiving a force greater than the bias force. A circuit of the switch is closed responsive to the input device moving from the first state to the second state. The switch outputs an actuation signal responsive to the circuit being closed. The body includes a tensioner and a base including a strap receiver opposite the tensioner. The actuator moves the tensioner from a first tensioner position to a second tensioner position further from the strap receiver based on a movement force greater than the bias force.

The invention relates to a drive unit for a strapping device for strapping an item to be packed with a plastic tape which is laid around it, having a motorized tensioning device and a motorized welding device for the plastic tape, wherein the tensioning and the welding device can be driven by the same electric motor which can be brought alternatively into an operative connection with said devices with freewheels being connected in between. The problem has occurred in drive units of this type that they are relatively complicated to assemble and have problematic operational reliability under certain boundary conditions. In order to bypass said problems, it is proposed to provide the electric motor with at least one shell extension which protrudes beyond it at one axial end, with the result that the drive elements which have up to now been mounted separately in the housing of a strapping device can be supported directly on the electric motor which then acts as a drive unit.

The invention discloses a tensioner comprising a belt shaft, a first bracket and a second bracket, a belt shaft hole is provided at a front end of the first bracket, the belt shaft passes through the hole and is hinged with the first bracket; a surface of the belt shaft is provided with a ratchet fixedly connected thereto and gaskets provided on two sides of the ratchet; one end of the second bracket is provided with a clamping portion, the clamping portion clamps two ends of the belt shaft and protrudes outwardly to form an accommodating cavity, balls are provided inside the accommodation cavity, and the balls are installed on an outer gasket of the belt shaft. The plastic gaskets greatly reduce the friction between the ratchet and the bracket, the balls provide a certain degree of freedom for the belt shaft to prevent the belt shaft from jamming.

A baling press having a rope tying system with a loop supply member for forming a loop of the second rope material across the bale pressing channel to the first side of the bale pressing channel and a loop of the first rope material at the first side. The loop supply member is suspended on the second side of said bale pressing channel and movable along a straight path between an extended position projecting across the bale pressing channel and a retracted position.

The loop supply member has a turn guide for forming and guiding the loops in the first and second rope materials and a spreader for, when the loop supply member is in the extended position, holding the rope materials guided so that portions in the knotting area are spaced from a free end portion of the loop supply member.

A wire release mechanism for securing an end of a wire during a wire tying cycle is provided. The wire release mechanism may secure a first end of a wire around a bale of recycled material during knotting of the wire. The wire release mechanism may include a wire release portion having an engaging surface and the wire release portion may be movable between an open and closed position. The wire release mechanism may further include a gripping arm movable between a first position and a second position and having a retractable surface. The engaging surface may disengage the wire based on movement from the closed position to the open position. Further, the retractable surface may engage against the first end of the wire based on movement from the first position to the second position.
