Abstract
Abstract This invention consists of a vertically disposed cylindrical body around which yarn is wrapped by mechanism rotated by an electric motor. The aforesaid yarn is held in place on the side of the aforesaid body by means of two opposed and vertically mounted rubber belt conveyors which are rotated by means of longitudinally disposed cylinders. At the same time a strip of paper, having glue on one side thereof, is fed to and pressed against the aforesaid yarn on the body and a plurality of threads are also fed to and pressed against the yarn on the other side of the body with the resulting desired tape coming down from the bottom of the body between two rollers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
A machine for manufacture of a fiber reinforced tape having longitudinal fibers and transverse fibers by a winding method comprising: a thread receiving body having a circular portion thereon; a pair of belt conveyors mounted on opposite sides of the body; means for moving the belt conveyors along the length of the body; means for winding a transverse thread around the circular portion of the body over the belt conveyors; a first roller oN one side of the body and rotatable about an axis transverse to the length of the body for feeding a plurality of longitudinal threads along one side of the body; a second roller on the other side of the body from the first roller and rotatable about an axis transverse to the length of the body for feeding a tape along the other side of the body; and a pair of securing rollers at the opposite end of the body from the means for winding for pressing the tape, the transverse thread and the longitudinal threads together.
Claim 2
Dependent Claim
171 words
A machine for manufacture of a fiber reinforced tape having longitudinal fibers and transverse fibers by a winding method comprising: a thread receiving body having a circular portion thereon; a pair of belt conveyors mounted on opposite sides of the body; means for moving the belt conveyors along the length of the body; means for winding a transverse thread around the circular portion of the body over the belt conveyors; a first roller oN one side of the body and rotatable about an axis transverse to the length of the body for feeding a plurality of longitudinal threads along one side of the body; a second roller on the other side of the body from the first roller and rotatable about an axis transverse to the length of the body for feeding a tape along the other side of the body; and a pair of securing rollers at the opposite end of the body from the means for winding for pressing the tape, the transverse thread and the longitudinal threads together.
Claim 3
Dependent Claim
39 words
A machine as defined in claim 1 wherein the means for winding comprises an L-shaped tube through which the transverse thread passes and means for rotating the L-shaped tube with its end adjacent the circular portion of the body.
Claim 4
Dependent Claim
38 words
A machine as defined in claim 1 wherein the means for moving the belt conveyors comprises a pair of drive rollers, each drive roller engaging the respective belt conveyor on the outside face thereof over the transverse thread.
Claim 5
Dependent Claim
23 words
A machine as defined in claim 3 wherein the first and second rollers are mounted between the drive rollers and the securing rollers.
Claim 6
Dependent Claim
51 words
A machine as defined in claim 4 wherein the means for winding comprises an L-shaped tube through which the transverse thread passes and means for rotating the L-shaped tube with its end adjacent the circular portion of the body on the opposite side of the drive rollers from the securing rollers.
