Abstract: The invention relates to a method for producing strapping. A strapping band (4) is first guided about at least one packaging piece, tightened, and equipped with a closure at band ends (4a, 4b) to be connected in a closure unit (1). Furthermore, at least one sensor (7) connected to a control unit (8) is provided in the closure unit (1). One or more closure parameters are detected by means of the control unit (8) using the sensor (7), and the closure unit (1) is correspondingly actuated. According to the invention, the sensor (7) is designed as a load cell (7) which is let into a compression ram (6a, 6b) of the closure unit (1).

Abstract: A strapping tool has a tensioner for tightening a strap, a sealer for fixing together ends of the strap, a base, and a drive mounted on the base for operating the tensioner and sealer. The sealer or tensioner is a module removably attached to the base. A transponder is provided on the module and a reader on the base for wirelessly communicating with the transponder. A controller is connected to the reader for operating the tool.

Abstract: A strapping apparatus has a frame, a single drive motor carried on the frame and having an output shaft, a feed roller connected to the motor and rotatable on the frame, and a tightening roller connected to the motor and rotatable on the frame. A strap from a supply is spanned over and passes between the feed and tightening roller to the object. A lever is pivoted on the frame parallel to the feed and tightening axes for movement between two angularly offset end positions. A feed counter roller freely rotatable on the lever is engageable in one of the end positions with the feed roller to pinch and advance the strap toward the object, and a tightening counter roller rotatable on the lever is engageable in the other of the end positions with the tightening roller to pinch and pull the strap away from the object.

Abstract: The present invention relates to a plastics-material strapping band (4) for wrapping around one or more articles. The plastics-material strapping band has the following constituent parts: a) up to approximately 90% by weight polyester, b) approximately 1% by weight to 5% by weight polyolefin and c) approximately 5% by weight to 10% by weight fiber material. The invention also relates to a method for producing a plastics-material strapping band.

Abstract: A machine for wrapping a strap in one or two loops around a package has a support frame and first and second upright generally annular strap-guiding channels. The channels each have confronting ends defining a respective gap that are immediately adjacent each other, and the package is engageable within the annular channels. A single-loop guide fittable in the gap of the first channel has a guide groove extending in a single-loop mode between the ends of the first channel. A double-loop guide fittable in a dual-loop mode in the gaps of the first and second channels has first and second crossing guide grooves that extend between one of the ends of the first channel and one of the ends of the second channel and the second guide groove extending between the other of the ends of the first channel and the other of the ends of the second channel.

Abstract: A strapping machine has a housing carrying a mount attachable to an overhead balancer line, tensioning and sealing devices in the housing, and an elongated pivotal handle. An inner handle end is formed with an annular inlet passage and a radially throughgoing inlet port opening into the inlet passage. The handle also is formed with axially extending passages extending from the inlet passage to an outer handle end. A pneumatic motor in the outer handle end drives a transmission in the inner end of the handle in turn drives the devices in the housing. An inlet fitting on the housing is connectable to a compressed-air supply line. A conduit has one end communicating with the inlet fitting and an opposite end opening radially inward into the inlet port of the handle. The outer handle end is formed with an outlet opening for venting air from the motor.

Abstract: A strapping connection for a pair of longitudinally extending and transversely overlapping strap ends has a pair of longitudinally extending and interengaging hook formations formed as transversely pushed-out regions of the strap ends and permitting limited movement of the strap ends in one longitudinal direction. In addition the ends are formed in the pair of hook formations with transversely interengaging lock formations fitting transversely snugly together and prohibiting relative longitudinal movement of the strap ends.

Abstract: A strapping apparatus for securing a tape around a package has a housing, a support roll rotatable on the housing, a tube shaft pivotal on the housing adjacent the support roll about a tube-shaft axis, and a drive shaft rotatable in the tube shaft about a drive-shaft axis parallel to and offset from the tube-shaft axis. A first drive roll on the drive shaft carries a friction layer bearing axially offset from the drive-shaft axis on the housing. A first drive connected to the drive shaft rotates same and the first drive roll in a clamping direction and thereby oppositely rotates the tube shaft about the tube-shaft axis into an end position and also can rotate the drive shaft and the first drive roll in an opposite freeing direction to thereby oppositely rotate the tube shaft about the tube-shaft axis into another end position.
