Supported strap twist device

摘要

A supported strap twist device reorients a strap along a strap path. The device includes an inlet, an outlet and a reorienting section. The reorienting section includes a body having entrance and exit ends and a transition section therebetween. The transition section has a through-bore having a varying cross-sectional shape defining a race. The race has, at a first end, an opposed inwardly pinched circular profile defining a gap. The circular profile thins along the race toward an hourglass profile, and has, at a second end, an elongated shape. The gap has a substantially constant width along the race. The strap enters the first end at an angle relative to the second end and is reoriented to a desired orientation at the second end. The strap is supported by the race as it traverses therethrough.

1. A supported strap twist device, comprising:
an inlet; an outlet; and a reorienting section having a body having an entrance end, an exit end and a transition section therebetween, the transition section having a through-bore having a varying cross-sectional shape defining a race, the race having, at a first end thereof, an opposed inwardly pinched circular profile, in which diametrically opposed lobes are pinched toward one another to define a gap, top and bottom portions of the circular profile thinning out along the race toward an hourglass shape, and top and bottom portions of the hourglass shape further thin toward an elongated shape at a second end thereof, the gap having a substantially constant width along the race, wherein strap enters the first end at an angle relative to the second end, and wherein the strap is reoriented to a desired orientation at the second end, the strap being supported by the race as it traverses therethrough.
