Abstract
Abstract A fabric layering machine for movement along a layering table, comprising a frame, mounting means carried by said frame for mounting a supply of fabric, a pair of draw-off rollers arranged to provide a nip therebetween and readily removable from an operative position on said frame, and power means operable to rotate said draw-off rollers in opposite senses to each other for pulling through said nip a web of fabric extending from said supply of fabric.

Total Claims: 13
Claim 1
Independent Claim
264 words
A fabric layering machine for movement along a layering table, comprising a frame, mounting means carried by said frame for mounting a supply of a web of fabric, a pair of rotatable draw-off rollers positioned in proximity to each other so as to form a fabric-engaging nip therebetween and being detachably mounted in an operative position on said frame, guide roller means detachably fastened on said frame above said draw-off rollers for guiding said fabric web into the nip between said draw-off rollers, and power means operable to rotate said draw-off rollers in opposite senses to each other for pulling through said nip said web of fabric extending from said supply of fabric, a feed roller carried by said frame and disposed to feed said web towards the nip between said drawoff rollers, further power means operable to rotate said feed roller for feedinng forward said web, a deflection roller carried by said frame and disposed proximate the surface of said feed roller for causing said web to contact said feed roller over an arc of contact, a pressing roller carried by said frame for cooperating with said deflection roller when said web extends around said feed roller so as to cause said web to contact said feed roller, and adjustable holding means for holding the pressing roller for adjusting the position of said pressing roller relative to said feed roller, said detachably mounted guide roller means and draw-off rollers adapted to be selectively removed and replaced by other operative components for converting said machine from single-layer fabric to tubular fabric operation, and reversely.

Claim 3
Dependent Claim
32 words
A fabric layering machine as claimed in claim 1, in which said draw-off rollers are mounted in a draw-off head carried by said frame, said head being detachably mounted on said frame.
Claim 4
Dependent Claim
29 words
A fabric layering machine as claimed in claim 2, in which said draw-off head includes adjustment means for adjusting the position of said draw-off rollers relative to each other.
Claim 5
Dependent Claim
46 words
A fabric layering machine as claimed in claim 2, in which said frame includes attachment-bar means extending transversely of the direction of movement of the machine along said table, and said draw-off head detachably mounted on said frame by hook means engaging over said attachment-bar means.
Claim 6
Dependent Claim
41 words
A fabric layering machine as claimed in claim 1, comprising movable slide means connected to said attachment bar means for supporting said draw-off rollers so as to be carried by said frame to be raisable and lowerable relative to said table.
Claim 7
Dependent Claim
47 words
A fabric layering machine as claimed in claim 1, in which said power means includes transmission means detachably connected to one of said draw-off rollers for transmission of drive thereto, and the other of said draw-off rollers is drivably coupled to said one of said draw-off rollers.
Claim 8
Dependent Claim
21 words

Claim 11
Dependent Claim
39 words
A fabric layering machine as claimed in claim 1, in which said mounting means includes positioning means operable to move said mounting means relative to said frame transversely of the direction of movement of the machine along the table.
Claim 12
Dependent Claim
27 words
A fabric layering machine as claimed in claim 1, including a web-severing device adapted to be detachably fastened to said frame in place of said draw-off rollers.
Claim 13
Dependent Claim
27 words
A fabric layering machine as claimed in claim 1, comprising a layering head adapted to be detachably fastened to said frame in place of said draw-off rollers.
