United States Patent 0 29 Claims. (Cl. 112-2) 10 ABSTRACT OF THE DISCLOSURE A combined automatic sewing assembly having feeding means including reciprocable feeder -foot means operative to contact the topmost piece of porous cloth that is stacked in a pile. The reciprocable feeder foot means separate the topmost workpiece from the remainder of the pile in a lifting action with the feeder foot means having adhesive means for engagement with the topmost workpiece in order to achieve the aforesaid lifting action. The feeder foot means also have vacuum means that are activated during the lifting action in order to assist the adhesive means in maintaining contact with the workpiece during the lifting action. In another embodiment of the invention a pin extends from the vacuum means to engage the workpiece and assists in urging the workpiece forwardly following the aforesaid lifting action in order to project the workpiece towards feed rollers. In another embodiment of the invention the adhesive means are dispensed with, such that the lifting and feeding action is achieved with the vacuum means-pin combination.

Other features may be associated with the feeding means including a sewing station, cutting means and stacking means.

This application is a continuation-in-part application based on application Ser. No. 467,911 filed June 29, 1965, and entitled, Improved Automatic Sewing Assembly, now abandoned.

This invention relates to a sewing apparatus and has as its objective the provision of an improved automatic sewing machine assembly.

With the rise of foreign competition in the textile field, it has become incumbent upon domestic manufacturers to increase productivity in order to overcome a financially unfavorable wage differential.

Therefore, many attemps have been made in the past years to automate the various sewing processes.

Such prior attempts have been successful to some degree, but the ultimate goal, namely, to achieve a sewing apparatus which is fully automated is yet to be achieved.

In Jacobs Patent No. 3,223,059 there was disclosed and claimed an automatic sewing apparatus which basically comprised a feeder station, a sewing station, a cutting station and a stacking station. As a part of the assembly of the automatic sewing apparatus of said Patent No. 3,223,059, there was provided a feeder foot which was actuated by a feeder belt assembly that included adhesive means. When the feeder foot went through a rocking cycle, it pressed an area of adhesive tape against the upper surface of the topmost piece of stacked pieces of goods. As the feeder foot stepped upwardly and forwardly, it carried said topmost piece of goods with it to rollers which then conveyed the piece of goods towards a sewing station. When the piece of goods approached the sewing station a sewing machine was turned on through the uti-' lization of photosensitive means. At the same time bind- "ice ing was fed to the sewing machine in order to be sewn to a piece of goods. After the sewing operation was completed, the sewn goods were further advanced toward a cutting station. Additional photosensitive means were utilized to actuate a cutter in the cutting station at the proper time so that the sewn binding would be severed at a desired point. The goods were finally conveyed to a stacking station preparatory to the initiation of further operation or final packing.

The automatic sewing apparatus of said Patent No. 3,223,059 has operated satisfactorily and has achieved the objectives set forth therein.

However, certain improvements in the basic mechanism disclosed in said Patent No. 3,223,059 have been made such that the operation of the combined automatic sewing apparatus is now even more satisfactory and more dependable, and furthermore these improvements have greatly increased the versatility of the basic mechanism.

It is, accordingly, a prime objective of the present invention to provide a combined sewing assembly which is fully automatic.

A further object of the present invention is to provide a combined automatic sewing assembly with complementary feeding means, sewing means, cutting means and stacking means.

A still further object of the present invention is to provide a combined feeding means for use with an automatic sewing apparatus.

Yet another object of the present invention is to provide a combined automatic sewing assembly which incorporates air cylinders to provide the various basic movements required for operation of the machine.

A still further object of the present invention is to combine with a combined automatic sewing assembly, folding means and holding means which are operative through the strategic positioning of a plurality of air jets.

A still further object of the present invention is to provide improved cutting means for use in a combined automatic sewing assembly.

The foregoing as well as other objects of the invention are achieved by providing a combined automatic sewing assembly which basically comprises a feeder station, a sewing station, a cutting station and a stacking station.

In the specific embodiment to be detailed hereinafter, a continuous binding is automatically sewn to a cut sleeve, but it should be understood that many other sewing variations obtainable with the present invention will readily occur to those skilled in the art.

The feeding station basically comprises a platform for holding the stacked cut sleeves, and a feeder assembly including a feeder foot for depositing the cut sleeves, oneby-one, onto a conveyor belt to the sewing machine.

The sewing machine is automatically activated by photosensitive means, and the cutting means are also activated by photosensitive means.

A stacking station is provided to automatically stack the product after the sewing and cutting operations have been completed.

Automatic stopping controls are associated with both the feeder platform and stacking means for emergency purposes as when the feeder supply is exhausted or the adhesive means have been wound to capacity on a takeup roll. Various other safety features and warning devices are associated with the present invention, such as, warning lights and automatic turn-off devices in the event undesirable conditions develop.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
