摘要： 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. The apparatus, in one form, comprises a loading tube which is arcuately reciprocal toward and from the loading position and, in another, a loading tube which is rectilinearly reciprocal toward and from the loading position.

摘要： 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. With the old bobbin in the rewind position, the remaining, unused thread is first extracted from it, and then the thread supply is guided into engagement with the empty bobbin in preparation for rewinding. The rewinding operation is carried out while the filled bobbin is being used in the sewing operation, so that there is continuity of operation of the sewing machine.
摘要翻译： 本发明涉及用于缝纫机的自动筒管重绕。 提供了一种两站机构，使得筒管能够从卷绕位置转移到缝纫位置，其中一个筒管始终处于每个位置。 当筒管排出时，将该筒管及其壳体从缝纫机上取出，同时将填充的筒管从卷绕位置移除并与其外壳相结合。 然后将梭芯位置反转，使填充的筒管及其壳体插入缝纫机中，同时将刚卸下的线轴从壳体分离并插入卷绕位置。 填充的线轴保持连接到主线供应器，直到其插入缝纫位置，使得线可以被引导和控制，直到由缝纫机构拾取，从而避免了手动干预的需要。 随着旧卷轴位于倒带位置，首先从其中取出剩余的未使用的螺纹，然后将螺纹供给引导与空筒管接合以准备倒卷。 在缝纫操作中使用填充的线轴时进行倒带操作，使缝纫机具有连续的操作。

摘要： 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. In conjunction with the new mechanism, there is provided an advantageous, economically feasible control system for effecting highly precise measurement of the bobbin thread, as it is fed to the bobbin spool during the reloading operation. precise control over the thread length guarantees that there is sufficient thread in the bobbin spool to complete the work unit, while avoiding wastage of thread tails.
摘要翻译： 本发明涉及在工作单元的装载之间的间隔内，在锁缝缝纫机中自动重新填充筒管。 在由单个工件或多个工件组成的预定工作单元缝制之后，在筒管卷轴上预先测量的螺纹长度被排出。 当机器操作者将新的工作单元放置在适当位置以进行缝合时，本发明的机构在原位通过从有效连续的供应源抽出的精确测量的底线长度来重新填充空筒管。 为此目的提供的机构本身通常已知的是以改进的，简化的和更紧凑的布置布置，适合于并入到业内可用的各种商业锁缝缝纫机中。 结合新机构，提供了一种有利的，经济上可行的控制系统，用于在重新加载操作期间将其提供给线轴卷轴时，对底线进行高精度测量。 对螺纹长度的精确控制确保了梭芯线筒中有足够的螺纹来完成工作单元，同时避免了螺纹线的浪费。

摘要： 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. The neatness and uniformity of the folding operations makes the equipment easily adaptable for automatic packaging of the folded product.

摘要： A garment stacker, having a plurality of conveyor belt assemblies, is attached to a worktable. Each assembly has two conveyor belts with one end of each sharing a common axis. All of the conveyor belts are provided with a plurality of flexible cleats for engaging the garment. One of the belts in each assembly is movable between a position away from the worktable, and a position near the worktable, where the cleats will engage a garment deposited on the worktable and pull it toward the other belt. The other belt in each assembly is nearly vertical and is positioned adjacent to a parallel slide. The garment is fed by the first belt into the space between the slide and the cleats on the vertical belt, which engage the garment and move it up the slide. The garment is then discharged over the top of the slide and onto a door. When the door is opened, the garment is dropped onto other garments, while maintaining its orientation so as to form a stack of oriented garments.
