Abstract
Abstract Apparatus for simultaneously providing a multiplicity of similarly sized pieces of sheet material in a stacked relationship in preparation for a multiple piece cutting operation employed in the garment and piece good industry. A movable carriage and clamping arrangement withdraws in one pass, a plurality of overlying lengths of sheet material from a single supply roll or bolt of material. Further provision is made to individually sever the overlying lengths after the withdrawal takes place.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
288 words
Apparatus for simultaneously providing a plurality of overlying segments of flexible sheet material from a continuous supply source comprising: a. a first set of spaced elongated separation means; b. a second set of spaced elongated separation means selectively moveable from a first position generally proximate said first set of separation means to a selected second position generally remote from said first set of separation means, the distance between said second set of separation means and said first set of separation means when said second set of separation means is in said selected second position being substantially equivalent to that of the selected length of each segment of the sheet material; c. each said first and second set of separation means being disposed with respect to itself and the other whereby when said second set of separation means is in said first position, the forward end of the sheet material can be alternately interwoven between respective separation means in each said first and second sets whereby upon securing the forward portion of the sheet material to the apparatus after the sheet material has been interwoven between said respective separation means in each said first and second sets, the said movement of said second set of separation means to said second position will simultaneously withdraw a plurality of segments of sheet material from the continuous supply source, the segments being in a generally stacked overlying relationship to each other and each segment being substantially the same length; and d. means for securing the forward portion of the sheet material to said apparatus whereby the movement of said second set of separation means to said second position will withdraw the plurality of segments of sheet material from the continuous supply source.

Apparatus for simultaneously providing a plurality of overlying segments of flexible sheet material from a continuous supply source comprising: a. a first set of spaced elongated separation means; b. a second set of spaced elongated separation means selectively moveable from a first position generally proximate said first set of separation means to a selected second position generally remote from said first set of separation means, the distance between said second set of separation means and said first set of separation means when said second set of separation means is in said selected second position being substantially equivalent to that of the selected length of each segment of the sheet material; c. each said first and second set of separation means being disposed with respect to itself and the other whereby when said second set of separation means is in said first position, the forward end of the sheet material can be alternately interwoven between respective separation means in each said first and second sets whereby upon securing the forward portion of the sheet material to the apparatus after the sheet material has been interwoven between said respective separation means in each said first and second sets, the said movement of said second set of separation means to said second position will simultaneously withdraw a plurality of segments of sheet material from the continuous supply source, the segments being in a generally stacked overlying relationship to each other and each segment being substantially the same length; and d. means for securing the forward portion of the sheet material to said apparatus whereby the movement of said second set of separation means to said second position will withdraw the plurality of segments of sheet material from the continuous supply source.
Claim 3
Dependent Claim
26 words
The apparatus as set forth in claim 1 wherein at least a portion of said separation means in at least one said set thereof are rotatable.
Claim 4
Dependent Claim
48 words
The apparatus as set forth in claim 1 wherein each said first and second set of spaced elongated separation means comprises a plurality of rollers in a substantially vertical alignment on a frame means, each said roller having a length at least that of the flexible sheet material.
Claim 5
Dependent Claim
34 words
The apparatus as set forth in claim 1 wherein said means for securing the forward end of the sheet material is disposed relatively stationary to the movement of said second set of separation means.
Claim 6
Dependent Claim
38 words
The apparatus as set forth in claim 1 wherein the continuous supply of sheet material and said means for securing the forward portion of same are both carried by and moveable with said second set of separation means.
Claim 7
Dependent Claim
38 words
The apparatus as set forth in claim 1 further including means for severing the plurality of segments of sheet material into individual lengths, said means for severing proximate to at least one of said sets of separation means.
Claim 8
Dependent Claim
42 words
The apparatus as set forth in claim 1 wherein at least a portion of said separating means in at least one of said sets thereof can be selectively replaced with means for securing a forward portion of the sheet material thereto. Pg,16
Claim 9
Dependent Claim
44 words
The apparatus as set forth in claim 1 further including means for releasing said separating means from their respective location in each said set thereof whereby each said set of separating means can be selectively brought substantially together from the said spaced relationship thereof.
Claim 10
Dependent Claim
18 words
The apparatus as set forth in claim 2 further including means for power driving said rotatable separating means.
Claim 11
Dependent Claim
42 words
The apparatus as set forth in claim 1 further including power driven means for withdrawing the continuous supply source of flexible sheet material during said movement of said second set of separation means from said first position to said second position thereof.
Claim 12
Dependent Claim
24 words
The apparatus as set forth in claim 5 wherein at least a portion of said separation means in said second set thereof are rotatable.
Claim 13
Dependent Claim
16 words
The apparatus as set forth in claim 11 wherein said rotatable separation means is power driven.
Claim 14
Dependent Claim
44 words
The apparatus as set forth in claim 5 further including means for power driving the withdrawal of the continuous supply source of flexible sheet material during said movement of said second set of separation means from said first position to said second position thereof.
