Abstract
Abstract A method and apparatus for reorienting the material of a layer of plastic, paper, or a multiplicity of natural or synthetic threads, tapes or filaments such that the longitudinal axis of the layer, which initially coincides with its direction of travel, is eventually at right angles to its direction of travel. In accordance with the method and apparatus of the invention, a plurality of belts move over a stationary mandrel in a helical path. The layer is wrapped about the belts and stationary mandrel such that the longitudinal axis of the layer and its direction of movement is at right angles to the longitudinal axis of the belts. Gripper cables cooperate with the belts to grip the layer just prior to its being cut as it leaves the mandrel. The result is a newly formed layer comprising reoriented abutting pieces of the material held together by the belts and gripper cables. These pieces are as long as the width of the newly formed layer, but the longitudinal axis of the pieces is now at right angles to the direction of movement of the new layer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
A method for changing the orientation of a layer of material having its longitudinal axis parallel to its direction of travel comprising driving a plurality of spaced narrow endless carrier belts longitudinally in a helical path about a stationary mandrel, wrapping said layer about and upon said mandrel and belts so that the longitudinal axis of said layer is at right angles to the longitudinal axis of said belts, gripping said layer with a pair of endless gripping cables cooperating with a pair of said belts at what will become the edges of a reoriented layer and continuously cutting said layer between said pair of belts at approximately the location of initial gripping to form a reoriented layer consisting of a succession of pieces of said layer each having its longitudinal axis at right angles to the movement of said reoriented layer from said mandrel.
Claim 2
Independent Claim
145 words
A method for changing the orientation of a layer of material having its longitudinal axis parallel to its direction of travel comprising driving a plurality of spaced narrow endless carrier belts longitudinally in a helical path about a stationary mandrel, wrapping said layer about and upon said mandrel and belts so that the longitudinal axis of said layer is at right angles to the longitudinal axis of said belts, gripping said layer with a pair of endless gripping cables cooperating with a pair of said belts at what will become the edges of a reoriented layer and continuously cutting said layer between said pair of belts at approximately the location of initial gripping to form a reoriented layer consisting of a succession of pieces of said layer each having its longitudinal axis at right angles to the movement of said reoriented layer from said mandrel.
Claim 3
Independent Claim
159 words
An apparatus for changing the orientation of the material of a layer of material having its longitudinal axis parallel to its direction of travel comprising a stationary mandrel, a plurality of spaced narrow endless carrier belts, means to drive said belts in a helical path about and directly upon and in contact with said mandrel, means to wrap said layer about said mandrel and belts such that the longitudinal axis of said layer is at right angles to the longitudinal axis of said belts, a pair of endless gripping cables arranged to cooperate with a pair of adjacent belts to grip said layer, and means to continuously cut said layer at a location between said pair of gripping cables so as to form a reoriented layer consisting of a succession of pieces of material of said first mentioned layer each of which has its longitudinal axis at right angles to the movement of said reoriented layer from said mandrel
Claim 4
Independent Claim
159 words
An apparatus for changing the orientation of the material of a layer of material having its longitudinal axis parallel to its direction of travel comprising a stationary mandrel, a plurality of spaced narrow endless carrier belts, means to drive said belts in a helical path about and directly upon and in contact with said mandrel, means to wrap said layer about said mandrel and belts such that the longitudinal axis of said layer is at right angles to the longitudinal axis of said belts, a pair of endless gripping cables arranged to cooperate with a pair of adjacent belts to grip said layer, and means to continuously cut said layer at a location between said pair of gripping cables so as to form a reoriented layer consisting of a succession of pieces of material of said first mentioned layer each of which has its longitudinal axis at right angles to the movement of said reoriented layer from said mandrel
Claim 5
Dependent Claim
20 words
The apparatus of claim 1 wherein said mandrel has a plurality of longitudinally extending grooves over which said belts ride.
