Abstract: A method and apparatus are disclosed for forming and maintaining a fold or crease or a formed shape in or on a fabric piece while a product is being manufactured comprising the fabric. The method comprises the steps of applying an adhesive to selected locations on the fabric piece, forming the fabric piece into the desired configuration, compressing the fabric piece at the selected locations to adhere the selected locations thereof whereby the fabric piece is maintained in the formed, desired configuration during at least part of the manufacture of the product, and thereafter dissipating the adhesive. The method is especially suited to the manufacture of garments having separately attached pieces such as pockets, facings, cuffs, yokes, and the like, wherein to faciliate manufacture, the folds and creases are temporarily made in the pieces and are maintained during manufacture by the adhesive, which is dissipated in the final stages of manufacture of the garment, typically during steam pressing of the garment.

Abstract: Preprinted rectangular blanks of longitudinally stretch-oriented foam sheet material are formed into cylinders by a continuous folder and seamer and transferred onto mandrels on which they are shrunken by heat to assume the shape of the mandrel. In forming containers, means are provided to place bottom blanks on the mandrels prior to the loading of the cylinders thereon so as to shrink the cylinders to sidewall shapes overlying the bottom blanks. The top curl on containers such as drinking cups and food tubs is formed after shrink forming and the bottom seam of the container is also reinforced by ironing after shrink forming. A method of continuously forcing and filling containers on a continuous in-line basis is also provided.

Abstract: A pair of thermoplastic workpieces are spin welded by placing one element in a non-rotatable, reciprocable clamp. Another workpiece is press-fit onto the first workpiece and the clamp is shifted toward a continuously rotatable collet having radially inwardly closable jaws. A mandrel extends from the collet and projects beyond the jaws to guide the workpieces between the jaws. The mandrel is axially inwardly displaceable by the workpieces, with inward movement thereof being yieldably resisted by a spring to insure that radial shoulders on the workpieces are in abutment. When the other workpiece is positioned between the jaws, the jaws are closed radially into driving contact with such workpiece to substantially instantly rotate the latter at the speed of the collet relative to the one workpiece. Frictional heat thus generated melts the interface between the workpieces. When the other workpiece is released from the jaws, it adheres to the one workpiece.

Abstract: A contoured work top is provided as a new or replacement work surface to fit over an existing support structure such as a desk or table. The work top has a flat sheet of structural material with a top surface and a bottom surface. A second sheet of structural material is provided having a plurality of spaced apart, parallel raised ribs extending across the second sheet which is rigidly connected to the lower surface at tips of the raised ribs thus supporting the second sheet a spaced apart distance from the flat sheet. Also included is at least one flat strip of structural material extending across the second sheet perpendicular to the raised ribs and rigidly connected to the second sheet at locations between the raised ribs. The work top may also have side walls extending downwards from the edges of the flat sheet beyond the second sheet adapted to retain the work top in place on a supporting structure.

Abstract: Method and apparatus for patching or seaming thermoplastic mesh fabrics, such as used in the papermaking industry by means of an ultrasonic welding tool. The tool is provided with one or more tips having raised surface portions or projections adapted for contacting the plastic mesh at a plurality of spaced points whereby ultrasonic welding is accomplished without substantial disruption or dimunition of the generally uniform porosity inherent to the mesh fabric. The method modifications involve the use of templates for guiding the positioning and movement of the ultrasonic welding tips for both butt seaming and overlap seaming of the opposed edges of thermoplastic mesh fabric. In the butt seaming technique, the outermost weft filaments of the opposed edges of the plastic fabric are replaced by one heat stabilized filament and the picket ends of the fabric are interdigitated about this stable filament preparatory to the welding step.
