An improved method of fabricating disposable coverings such as surgeon's caps comprises applying elastic strips and adhesive along opposed edges of two lengths of sheet material, folding and securing the edges over the elastic strips, applying spaced elastic strips and adhesive along and straddling the center line of one of the lengths of sheet material, bringing the sheets together and securing them along their center lines with the applied adhesive, cutting the sheets apart along their center lines to produce two sub-lengths of material, and cutting and heat sealing the sub-lengths at spaced intervals across their lengths to produce disposable surgeon's caps. The invention also contemplates a disposable protective covering fabricated by this method.

Bonded seams for joining nonwoven, spunbonded polyolefin fabric to itself are prepared by overlapping of edge regions of the fabric with linen sides of the fabric in contact with one another and first applying heat and pressure along a seam line by means of ultrasonic energy and an embossed wheel, giving a lightly bonded strip. The strip is then folded against an adjacent surface, and heat and pressure are applied from the opposite side of the fabric and over the underlying folded-over strip. This procedure in effect merges the bond produced by the second application of heat and pressure with the first bond, giving a strong bond. Cleanroom and protective garments may be fabricated to include such seams, with the side of the seamed fabric that has a remaining cut edge at the seam being disposed on the inside of the garment. Such garments avoid release of microscopic particles such as occurs for stitched seams.

A sleeve arrangement on garments, protective aprons or protective clothing having a whole and unbroken front piece entails the material for the sleeves being in one piece and joined along a substantially coherent, preferably continuous join extending around both shoulders and straight across the upper and lower portion of the chest, and the two adjacent material segments lying within the join definition being removed to produce one common aperture for both sleeves.A method of manufacturing the sleeves of garments, protective aprons or protective clothing having a whole and unbroken front piece comprises stitching, glueing or welding the coherent sleeve piece to the front piece of the garment, preferably in a single continuous operation, along a substantially coherent, preferably continuous join extending around both shoulders and across the upper and lower portion of the chest, and removing the two adjacent material segments lying within the join definition to produce one common aperture for both sleeves.

A support frame for garments such as brassieres, swimsuits and the like, and a system for forming the support frames. The wire member of each support frame is formed in a preselected, prescribed configuration and plastic protective end caps are adhered to the wire member end portions in a selected manner. The wire end may be modified by a cutter assembly which includes guiding and aligning apparatus for properly locating the wire frame ends relative to spaced rotating saws to remove selected portions and define a centrally located protruding tip portion intermediate spaced shoulders.

A process for building a pile making mold by bonding a plurality of tubes or needles into a matrix, as well as the mold, are disclosed. The use of tubes to make a mold permits the selection of a wider variety mold and pile dimensions than can be obtained with conventional methods of forming cavities in a mold surface. A pile material made by this process is also described.

A method for attaching a garment gathering elastic ribbon comprising the steps of stretching the elastic ribbon, internally immobilizing the elastic ribbon in a stretched state, attaching the stretched elastic ribbon to the garment and causing the attached elastic ribbon to return to its original contracted state.
