Abstract
Abstract Feed wheeltype strap tensioning mechanism designed for providing a high tension on nonmetallic strapping without damaging the strapping. Instead of the normal line contact between the feed wheel and the strapping, the mechanism is arranged to provide an appreciable area of contact whereby the pulling and gripping force of the wheel is spread over a sufficient area of the strapping as to avoid damaging the same.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
Strap tensioning mechanism comprising a pair of opposed elements between which a length of strap may be positioned, means for relatively moving said elements toward each other, one of said elements having a cylindrical surface and the other having a surface which provides a line contact between the two elements upon light engagement therebetween, one of said elements being deformable so as to conform to the shape of the surface of the other under application of pressure whereby each element has more than a line contact with a strap squeezed therebetween, and said last mentioned element comprising a relatively thin deformable metal facing secured to an underlying resilient portion.
Claim 2
Dependent Claim
109 words
Strap tensioning mechanism comprising a pair of opposed elements between which a length of strap may be positioned, means for relatively moving said elements toward each other, one of said elements having a cylindrical surface and the other having a surface which provides a line contact between the two elements upon light engagement therebetween, one of said elements being deformable so as to conform to the shape of the surface of the other under application of pressure whereby each element has more than a line contact with a strap squeezed therebetween, and said last mentioned element comprising a relatively thin deformable metal facing secured to an underlying resilient portion.
Claim 3
Dependent Claim
34 words
The strap tensioning mechanism set forth in claim 1 comprising means for rotating the element having the cylindrical surface when the two elements are pressed toward one another with a strap portion located therebetween.
Claim 4
Dependent Claim
21 words
The strap tensioning mechanism set forth in claim 2 wherein the metal facing is on the element having the cylindrical surface.
Claim 5
Dependent Claim
27 words
The strap tensioning mechanism set forth in claim 2 wherein the metal facing is on the element other than the one defined as having a cylindrical surface.
Claim 6
Dependent Claim
20 words
The strap tensioning mechanism set forth in claim 1 wherein both said elements have a relatively thin deformable metal facing.
Claim 7
Dependent Claim
19 words
The strap tensioning mechanism set forth in claim 3 wherein said metal facing has a roughened strap engaging surface.
