Abstract

Abstract A wire or band strapping machine comprises a driven roll pair for feeding a wire or band toward a guide loop about an object to be strapped, a driven roll pair for reversing the direction of movement of the wire or band to draw the same out of the guide and about the object, and tension means for tightening the wire or band in that reversed direction. The tension means is disposed between the two roll pairs, with the feeding pair disposed closer to the loop than the reversing pair with respect to the direction of travel of the wire or band. The wire or band approaches the loop along a horizontal U-shaped path with the feeding and reversing roll pairs operating on the upper and lower horizontal legs of that path, respectively, and the tensioning means acting downwardly on the wire or band in the bend of its U-shaped path.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 136 words
In a wire or band strapping machine comprising means guiding a wire or band about a looped path, means feeding said wire or band to said path, means holding the free end of the wire or band when said end has reached the end of the looped path, means for reversing the direction of movement of the wire or band to withdraw the wire or band to tighten the wire or band about an object to be strapped, and a tension device for tightening said wire or band about said object; the improvement in which said tension device is positioned between said feeding means and said reversing means and said feeding means is disposed closer to said looped path than is said reversing means with respect to the direction of movement of said wire or band.
Claim 2
Dependent Claim 136 words
In a wire or band strapping machine comprising means guiding a wire or band about a looped path, means feeding said wire or band to said path, means holding the free end of the wire or band when said end has reached the end of the looped path, means for reversing the direction of movement of the wire or band to withdraw the wire or band to tighten the wire or band about an object to be strapped, and a tension device for tightening said wire or band about said object; the improvement in which said tension device is positioned between said feeding means and said reversing means and said feeding means is disposed closer to said looped path than is said reversing means with respect to the direction of movement of said wire or band.
Claim 3
Dependent Claim 157 words
A machine as claimed in claim 1, said means for feeding the wire or band comprising a driven roller, a freely rotatable roller, and means for urging said freely rotatable roller toward said driven roller; said reversing means comprising a driven roller, a freely rotatable roller, and means for urging said freely rotatable roller toward said driven roller, the second mentioned driven roller rotating relative to the band in a direction opposite to the direction of the first-mentioned driven roller, said first driven roller being disposed a distance above said second driven roller, an endless member interconnecting both said driven rollers, a motor for driving one of said driven rollers, further rollers deflecting the wire or band into the shape of a horizontal U whose horizontal legs pass through said driving means and reversing means and whose upright bend passes through said tension device, said tension device acting vertically to impose tension on said wire or band.
