| titleOfInvention | Sheet production system with hem expander |
| abstract | SHEET PRODUCTION SYSTEM WITH HEM EXPANDER ABSTRACT OF THE DISCLOSURE Disclosed is a method of cutting and hemming sheet material, the steps of moving sheet material along its length from a supply into a cutting station, clamping the leading and trailing portions of the segment of sheet material in the cutting station against a first pair of parallel conveyor tapes, cutting the segment of sheet material in the cutting station away from the supply, moving the cut segment of sheet material parallel to its cut edges with the parallel conveyor tapes out of the cutting station, progressively folding at least one of the cut edge portions of the cut segment of sheet material upwardly onto a plat-form over the cut segment of sheet material as the cut seg-ment is moved parallel to its cut edges, holding the cut edge portion on the platform from movement in a direction across the length of its cut edges, moving the body portion of the cut segment of sheet material toward the fold in the sheet material, directing a flow of fluid beneath the platform toward the fold to expand the folded portion of the sheet material, continuing the movement of the segment parallel to its cut edges so as to progressively move the cut edge portion off the platform, and sewing through the folded over edge portion and the body portion of the sheet material to form a hem in the sheet material. |
