Patent number: 4248414Abstract: The disclosure relates to a panel folding machine and method, particularly for large panels. The panel is gripped at opposite leading corners and wound up by spaced rotating drums engaging opposite side edges of the panel. The drums are axially withdrawn, dropping the once-wound panel onto a lateral conveyor, where the panel, initially wound in a somewhat cylindrical form, assumes a flat folded condition. The once-wound panel is conveyed laterally until the leading lateral edge is engaged and gripped by a second stage winding drum, rotatable at right angles to the first drum. The panel is then wound in a second stage, in a generally cylindrical configuration. The second stage winding drum is retractable, and is withdrawn after the second stage winding operation, permitting the twice folded panel to drop onto a support conveyor. While on the support conveyor, the panel is flattened, to form a neat, rectangular product of uniform dimensions, which is then taken away for packaging.Type: GrantFiled: August 31, 1978Date of Patent: February 3, 1981Assignee: Automatech Industries, Inc.Inventors: Herman Rovin, Theodore Opuszenski, Joseph Pellicano

Patent number: 4244313Abstract: Thread-loading apparatus for loading a bobbin spool with a predetermined length of thread between sewing operations wherein there is a reciprocal loading tube arranged to receive and draw thread from a package of thread, deliver its leading end to the bobbin and project it onto the bobbin while the latter is being rotated at a high speed so as to be caught thereby and wound onto the bobbin; a slack-producing device for drawing a slack length of thread from the package of thread preparatory to a loading operation to thus eliminate the inertial resistance of the package of thread to giving up thread; a precisely-controlled thread measuring device employed to control the length of thread delivered to the bobbin; and a bobbin having peripherally-spaced flexible fingers on its hub for entraining the leading end of the thread delivered to the bobbin.Type: GrantFiled: April 17, 1978Date of Patent: January 13, 1981Assignee: Automatech Industries Inc.Inventors: Herman Rovin, Lawrence J. Levine, Theodore Opuszenski, Joseph Pellicano, Alan F. Swenson

Patent number: 4184652Abstract: A bobbin spool for an automatic sewing machine wherein a predetermined length of thread is wound onto the spool for each sewing operation comprising a hub, spaced parallel flanges at opposite ends of the hub, one of said hubs constituting a turbine wheel by means of which the bobbin may be rotated at a high speed by means of a jet of air and a traction engendering element covering an arcuate portion of the hub.Type: GrantFiled: April 28, 1978Date of Patent: January 22, 1980Assignee: Automatech Industries, Inc.Inventor: Herman Rovin

Patent number: 4117789Abstract: The disclosure relates to the automatic refilling of a bobbin spool, in a lock stitch type sewing machine, in the interval between the loading of work units. After sewing of a predetermined work unit, consisting of a single workpiece, or several workpieces, a premeasured thread length on the bobbin spool is exhausted. While the machine operator places a new work unit in position for sewing, the mechanism of the invention refills the empty bobbin spool, in situ, with a precisely measured length of bobbin thread, drawn from an effectively continuous supply source. The mechanisms provided for this purpose, in and of themselves generally known, are arranged in an improved, simplified and more compact arrangement, suitable for incorporation in a variety of commercial lock stitch type sewing machines available to the trade.Type: GrantFiled: September 14, 1977Date of Patent: October 3, 1978Assignee: Automatech Industries, Inc.Inventors: Herman Rovin, Lawrence J. Levine, Theodore Opuszenski, Joseph Pellicano, Alan F. Swenson

Patent number: 4002130Abstract: The disclosure is directed to automatic bobbin rewinding for sewing machines. A two-station mechanism is provided enabling bobbins to be transferred from a winding position to a sewing position, with one bobbin being at all times in each position. When a bobbin is exhausted, that bobbin and its case are removed from the sewing machine and, simultaneously, a filled bobbin is removed from the winding position and combined with its case. The bobbin positions are then reversed, enabling the filled bobbin and its case to be inserted in the sewing machine, while the just-removed bobbin is separated from its case and inserted in the winding position. The filled bobbin remains attached to the main thread supply until it is inserted in the sewing position, enabling the thread to be guided and controlled until picked up by the sewing mechanism, thus avoiding the need for manual intervention.Type: GrantFiled: September 22, 1975Date of Patent: January 11, 1977Assignee: Automatech Industries, Inc.Inventors: Herman Rovin, Theodore Opuszenski, Joseph Pellicano, Alan F.

Patent number: 3968760Abstract: The application discloses a method and apparatus for the substantially automated forming and sewing of hems on pillowcases and the like. The open end of a pillowcase is applied over hem folding forms, which first fold a large hem, and then a small blind hem is formed to conceal the raw edge of the fabric. Unique arrangements, covered in my related U.S. Pat. No. 3,865,058, are provided for effecting these hem folding operations. According to the invention, the pillowcase is then partially inflated with air and advanced circumferentially, while the hem structure is sewed into the article. The disclosure includes advantageous arrangements for the detection of an unsewn seam along the formed hem, and also advantageous arrangements for sensing the completion of the sewing operation. Automatic arrangements are provided for the insertion and sewing of a label, and the removal and stacking of the completed article after sewing.Type: GrantFiled: November 27, 1974Date of Patent: July 13, 1976Assignee: Automatech Industries Inc.Inventors: Herman Rovin, Rudolf Kreidel, Lawrence J.
