Abstract
Abstract Transfer tables are selectively provided at opposite ends of one of several stationary work tables, and an automatic controller is programmed to cause a gantry to spread sheet material from a roll on one transfer table onto the work table and a cross carriage on the gantry has a label applicator to apply labels to predetermined areas of the sheet material during return movement of the gantry onto the one transfer table. Another transfer table has a conventional cutter which is programmed to cut the sheet material after it is so spread, and labeled, following which cutting step the cutter head and its carriage can be returned to said another transfer table. Both of these transfer tables can be moved on tracks from these positions adjacent the ends of the said work table to other work tables.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
256 words
A method for spreading sheet material on a support surface of a cutting table between opposite first and second ends of said cutting table and applying labels to said sheet material in preparation for cutting a plurality of pattern pieces from said sheet material with each piece bearing an identifying label comprising at least the following steps: providing at the first end of the cutting table a spreading and labeling carriage that is movable over the support surface of said cutting table under automatic control; clamping a ply of sheet material adjacent a free end thereof to the spreading and labeling carriage while said carriage is located adjacent the first end of the cutting table and the sheet material is located off of said cutting table; moving the spreading and labeling carriage over the support surface from said first end of said cutting table toward said second end and drawing the clamped sheet material onto the support surface to spread the sheet material on said cutting table; releasing the clamped free end of the sheet material from the spreading and labeling carriage after said sheet material has been so spread; controllably returning the spreading and labeling carriage back to the first end of the table after releasing the material spread on the support surface; and applying labels from the spreading and labeling carriage to the areas of the spread sheet material from which pattern pieces are to be cut during the return movement of the spreading and labeling carriage to the first end of the table.
Claim 2
Independent Claim
256 words
A method for spreading sheet material on a support surface of a cutting table between opposite first and second ends of said cutting table and applying labels to said sheet material in preparation for cutting a plurality of pattern pieces from said sheet material with each piece bearing an identifying label comprising at least the following steps: providing at the first end of the cutting table a spreading and labeling carriage that is movable over the support surface of said cutting table under automatic control; clamping a ply of sheet material adjacent a free end thereof to the spreading and labeling carriage while said carriage is located adjacent the first end of the cutting table and the sheet material is located off of said cutting table; moving the spreading and labeling carriage over the support surface from said first end of said cutting table toward said second end and drawing the clamped sheet material onto the support surface to spread the sheet material on said cutting table; releasing the clamped free end of the sheet material from the spreading and labeling carriage after said sheet material has been so spread; controllably returning the spreading and labeling carriage back to the first end of the table after releasing the material spread on the support surface; and applying labels from the spreading and labeling carriage to the areas of the spread sheet material from which pattern pieces are to be cut during the return movement of the spreading and labeling carriage to the first end of the table.
Claim 3
Dependent Claim
72 words
The method of claim 1 further characterized by providing a roll of sheet material adjacent the first end of said cutting table, the step of clamping comprising clamping the free end of the sheet material in the roll to the spreading and labelling carriage, and unrolling said sheet material from the roll onto the support surface to so spread the material during the step of moving the carriage from said first end.
Claim 4
Dependent Claim
21 words
The method of claim 2 further characterized by severing said sheet material from the roll after it has been so spread.
Claim 5
Dependent Claim
54 words
The method of claim 3 further characterized by providing a roll of plastic air impervious sheet adjacent said sheet material prior to said clamping step for spreading with the sheet material, and said spreading and labelling carriage serves to mark said plastic air impervious sheet when in position on top of the sheet material.
Claim 6
Dependent Claim
47 words
The method of claim 1 further characterized by repeating said steps of clamping, moving, releasing, returning, and applying to spread another ply of sheet material on top of the previously spread ply and generate a multi-ply layup of sheet material for cutting with labels on each ply.
Claim 7
Dependent Claim
85 words
The method of claim 1 further including the steps of providing at the second end of said cutting table opposite the first end a cutting carriage for cutting pattern pieces from the sheet material spread on the support surface of said cutting table under automatic control; and controllably moving the cutting carriage over the support surface of said cutting table in cutting engagement with the spread sheet material after the step of returning the spreading and labelling carriage to the first end of the table.
