Abstract:
A bottom feeding mechanism, comprised of a plurality of caged balls and an endless belt in frictional driving contact therewith, is provided with an edge gage for uniformly positioning work pieces, especially flexible sheet material such as fabric, fed onto the balls. In addition to adjustably determining a selected marginal position and/or a line of feeding, for instance as required for hemming and/or stitching machines, the device is adaptable for turning over successive work pieces and aligning them in uniform manner.
Abstract:
A method of aligning a portion of textile fabric, whereby at least two movable gripping elements of a display device are brought alongside one another into contact with and fastened to a front edge of the portion of fabric and the gripping elements are moved substantially parallel to the surface of a display surface until the portion of fabric is laid out with one side flat on the display surface. In this case, the feed rate of the independently controllable gripping elements (2a, 2b) is so selected that the alignment of the portion of fabric (4) is variable by a feed difference (d, v) between the gripping elements (2a, 2b).
Abstract:
A device for picking up, turning over, folding and aligning a sleeve cloth that is continuously carried by a moving conveyer. The device comprises a jaw located above the upper surface of the moving conveyer and a lifting blade located below the bottom surface of a moving conveyer. The leading edge of the sleeve cloth is detected by a sensor that triggers the lifting blade to push a front portion of the cloth up and into the jaw which holds the cloth as the conveyer continues to move. The cloth is folded and aligned by the action of the conveyor belt and a first blower, which blows air on a top side of the cloth, and a second blower, which blows air on a bottom side of the cloth.
Abstract:
The disclosure relates to new methods and means for removing fabric plies one at a time from a stack, transporting the individual plies to a secondary location, precisely orienting and aligning the plies for a subsequent operation and, in some cases assembling one ply with another in preparation for a sewing operation. In one of its advantageous forms, the equipment specifically illustrated herein is especially useful for picking individual shirt cuff and liner plies from separate supply stacks, transporting them to a load station, and assembling the plies one on top of the other, in proper alignment and orientation for sewing. In a secondary mode, the equipment of the invention may be used to transport individual fabric plies, such as entire short sleeve shirt sections, to a sewing or other processing station.Incorporated in the comprehensive apparatus specifically disclosed are a plurality of inventive features in the form of significant sub-combinations capable of utilization in conjunction with other equipment and other processes.
Abstract:
A METHOD AND APPARATUS FOR AUTOMATICALLY REGISTERING FABRIC WORKPIECES FOR USE IN A PRODUCTION LINE TO BRING AN EDGE OR EDGES OF THE WORKPIECES INTO ACCURATELY KNOW LOCATIONS AND THEN FOR COMBINING THE REGISTERED WORKPIECES TOGETHER IN READINESS FOR JOINING THEM. FORCE IMPULSES ARE APPLIED TO THE WORKPIECE BY PULSATING AIR JETS FLOWING BENEATH THE WORKPIECE, THE PULSES OF AIR BEING GENERATED BY VALVING OR FLUTTERING VIBRATING REED ELEMENTS OR BOTH FOR AGITATING THE WORKPIECE TO REDUCE FRICTION EFFECTS AS THE WORKPIECE IS IMPELLED BY THE IMPULSES EDGEWISE TOWARD STOP SURFACES TO REGISTER IT. IN CERTAIN EMBODIMENTS PULSATING AIR JET UNITS ARE MOUNTED ON A MOVABLE OR INVERTIBLE HEAD WHICH ACCOMPLISHES THE DUAL FUNCTIONS OF REGISTERING A WORKPIECE AND THEN OF MOVING OR INVERTING THE WORKPIECE TO COMBINE IT WITH ANOTHER WORKPIECE. THE HEAD HOLDS THE REGISTERED WORKPIECE IN POSITION THEREON BY SUCTION DURING MOTION. IN MODIFIED EMBODIMENTS A REVOLVING SUCTION MEMBER IS MOUNTED UPON THE MOVABLE HEAD TO PROVIDE THE DUAL FUNTIONS OF REGISTERING AND COMBINING.
Abstract:
An arrangement for examining a textile material section is provided, more particularly of toweling goods, by visual inspection by an examiner. In this respect, the examining arrangement has a laying area arranged in the field of vision of the examiner, in which the material section can be positioned so that it is laid flat for examination of the first side of the material section. In addition, the examining arrangement includes a turning device (2, 3), by which the material section (4), starting from the position for examining the first side (8) of the material section (4), can be reversed in such a manner that the material section (4) can be positioned so that it is laid flat in the laying area (6) for examination of the second side (10) of the material section (4).

Abstract:
This disclosure teaches an apparatus for manufacturing and stacking hemmed fabric pieces (usually pockets) with the hems either lined or unlined. In the case of lined hemmed fabric pieces, pieces of a liner tape are fed in cut lengths in turn along a path. Limp fabric pieces (the pockets) are inserted manually by an operator and are positioned automatically each on one of the liner pieces. A hem is formed out of a margin of the fabric piece around its related liner piece and a terminal margin flap is tucked under itself. The hem is sewn along the terminal flap. The hemmed lined fabric pieces are then inserted in turn into a cartridge upwardly and the cartridge is revolved about a vertical axis as successive of the hemmed lined fabric pieces are inserted therein so that uneven height caused by the hems is distributed about the stack. In the case of unlined fabric pieces, the apparatus functions substantially the same in positioning the limp fabric pieces, hemming and stacking.
