32 Claims. (Cl. 154-13) This invention relates in general to improved methods and apparatus for cutting textile cloth sheet material and at the same time securing the cut fiber ends so as to provide one or more selvages at the points of cutting. The term selvage as hereinafter employed in the specification is intended to define and includesheet material woven or otherwise and having one or more edges extending longitudinally or transversely thereof, which edges are so formed as to prevent ravelling, roughening, or fraying.
The conventional procedure of sewing or stitching hems along'the cut edge of the sheet material ordinarily involves separate handling operations which add to the cost of certain types of specialty cloth items, such as diapers, towels, mechanics wipe-up cloths, and the like, especially where it is desired to cut ofi lengths of cloth from a web of sheet material in a continuous operation.
To avoid stitching, many proposals have been made for securing together the folded portions of a hem by means of an adhesive type binder employed either as a coating or impregnating agent, or utilized in the form of fusible fibers interwoven with the strands of the material itself. None of these proposals have proved to be a practical solution to the problem, due both to the objectionable characteristics which are imparted to the cloth hem, and to the difficulties in devising a mechanism for continuously carrying out periodic cutting, impregnating, and bonding steps in a satisfactory manner. 7
The present invention is concerned with the problem's indicated in connection with forming selvag'es, especially those problems surrounding such operations as cutting and securing a cloth hem with an adhesive type binder, and the invention aims to devise improved methods and apparatus for continuously forming selvages along cloth edges of both straight and curved shape. It is also an objectof the invention to devise a mechanism for rapidly and cheaply carrying out a novel sequence of operations in connection with a cloth hemming operation. Another object of the invention is to provide a mechanism capable of rapidly and efliciently forming a cloth hem which is of sufliciently rugged construction to undergo a great deal of hard usage, such as is encountered in repeated exposure and washings in chemical reagents, and which is, more over, capable of retaining a great deal of its normal textile characteristics. Still another object of the invention is to devise a method of handling hemmed cloth to facilitate folding and inspection operations.
These and other objects and novel features will be more fully understood and appreciated from the following description of preferred embodiments of the invention selected for purposes of illustration and shown in the accompanying drawings, in which Fig. 1 is a view in side elevation of an apparatus for handling a web or rollof cloth from which specialty cloth items are cut oif and provided with one or more selvages and subsequently carried away on a conveyor member;
