Abstract
Abstract Synthetic strapping made up of two layers of synthetic filament yarns with a bonding band formed of compatible synthetic material located between these layers and fusion bonded to the surfaces of the yarns with which the band is in contact, some of the band material extending into spaces between the yarns and into spaces between the filaments of the individual yarn.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
18 words
A synthetic strap as claimed in claim 1 in which the filaments of each yarn are molecularly oriented.
Claim 2
Dependent Claim
42 words
A synthetic strap as claimed in claim 1 iNcluding a synthetic binder band made of material compatible with the filament material wound around the filaments of each yarn and fused only to the outer filaments thereof with which it is in contact.
Claim 3
Dependent Claim
23 words
A synthetic strap as claimed in claim 1 in which said yarns and the band are formed of polyethylene or a copolymer thereof.
Claim 4
Dependent Claim
23 words
A synthetic strap as claimed in claim 1 in which said yarns and the band are formed of polypropylene or a copolymer thereof.
Claim 5
Dependent Claim
23 words
A strap as claimed in claim 1 in which said bonding band zigzags from one side edge to the other of said strap.
Claim 6
Dependent Claim
34 words
A strap as claimed in claim 1 in which the bonding band is in the form of a plurality of spaced relatively narrow, thin bands extending generally longitudinally of the strap in zigzag patterns.
Claim 7
Dependent Claim
46 words
A synthetic strap as claimed in claim 7 in which the zigzag patterns of the bonding bands are arranged so that the bands cross each other a plurality of times throughout the length of the strap and are fused to each other at the intersections thereof.
Claim 8
Dependent Claim
23 words
A synthetic strap as claimed in claim 7 in which said bonding bands are arranged to form diamond-shaped openings between said yarn layers.
Claim 9
Dependent Claim
37 words
A synthetic strap as claimed in claim 9 in which one diagonal of each diamond opening extends longitudinally of the strap and is no longer than the diagonal of said each opening extending transversely of the strap.
Claim 10
Dependent Claim
23 words
A synthetic strap as claimed in claim 7 in which said yarns and the band are formed of polyethylene or a copolymer thereof.
Claim 11
Dependent Claim
23 words
A synthetic strap as claimed in claim 7 in which said yarns and the band are formed of polypropylene or a copolymer thereof.
Claim 12
Dependent Claim
60 words
A synthetic strap as claimed in claim 1 including at least one substantially nonextensible thread extending generally longitudinally of the strap in a zigzag pattern and between and contacting the yarns of the strap, said thread being formed of material that fuses at a temperature above the fusion temperature of said bonding band material and yet adheres to the latter.
Claim 13
Dependent Claim
76 words
A synthetic strap as claimed in claim 6 including at least one substantially nonextensible thread extending generally longitudinally of the strap in a zigzag pattern and between and contacting the yarns of the strap, the zigzags of the thread being arranged so that said thread repeatedly crosses the zigzag-bonding band, said thread being formed of material that fuses at a temperature above the fusion temperature of said bonding band material and yet adheres to the latter.
