Abstract: A debris sweep and dry assist device is for use with a strapping machine. The debris sweep and dry assist device is positioned between the strapping machine and an associated strap supply. The device includes a body having a strap inlet and a strap outlet and defining a strap path therethrough. The body has a first wall at about the strap inlet and a second wall at about the strap outlet. The body has a first manifold and a plurality of first branches extending between the first manifold and the first wall to provide a plurality of flow paths from the first manifold to the environs through the first branches. A compressed is gas directed into the first manifold and flows out of the first branches, and is directed onto strap material at a location at about the strap inlet.

Abstract: A strapping machine that includes a strap chute defining an arch through which loads are conveyed, the arch having an entrance and an exit, infeed and outfeed conveyors positioned at the arch entrance and exit, respectively, the conveyors defining a work surface, and a strapping head disposed at about the arch for conveying the strap around the loads, tensioning the strap, and securing the strap. The machine further includes a sensor disposed above the work surface and a controller. During operation in a back-to-back mode, the infeed and outfeed conveyors are actuated to move a first, strapped load, and a second, to be strapped load, through the arch, wherein the outfeed conveyor is driven at a faster speed than the infeed conveyor to create a gap between the first and second loads.

Abstract: A self-adjusting stripper pin is for use in a strap chute for a strapping machine and includes a mount mounted to a fixed portion of the strapping machine, a reciprocating pin disposed in the mount for reciprocating movement relative to the mount and a pin spring disposed between the pin and the mount for biasedly mounting the pin to the mount. When the movable wall of the strapping machine is moved toward the fixed wall of the strapping machine, the pin moves out from the track to allow the strap to traverse therethrough and when the movable wall is moved away from the fixed wall, the pin is moved into the track to urge the strap out of the track. The spring positions the pin at about an outer edge of the track when the movable wall is moved away from the fixed wall.

Abstract: A dispenser having a start-assist for starting rotation of a coil for dispensing flexible material from the coil includes a frame, a support, a shaft mounted to the support for supporting the coil and configured for rotation with the coil and an arm mounted about the shaft by a one-way element. The arm is connected to the shaft for rotation such that when the arm rotates in a first direction the one-way element engages the shaft to rotate the shaft and when the arm rotates in a second, opposite direction the one-way element is disengaged from the shaft to permit the shaft to freely rotate. When the flexible material is pulled from the coil the arm is rotated in the first direction to begin rotation of the coil by tension in the flexible material.

Abstract: A strapping machine for positioning a strapping material around an associated load and sealing the strapping material to itself around the load, includes a frame, a feed assembly mounted to the frame for feeding, retracting and automatically refeeding the strapping material, a guide configured to receive the strapping material from the feed assembly, and a strapping head configured to receive the strapping material from the feed assembly via the guide and to position the strapping material around the load and seal the strapping material to itself around the load. The feed assembly includes one and only one pair of reversible feed elements and a drive. The machine includes a controller operably connected to the drive. The one and only one pair of reversible feed elements are configured to automatically feed, retract and refeed the strapping material upon an appropriate signal from the controller.
