Abstract: The invention pertains to a novel method of forming a flexible, tapered end on a thermoplastic molding strip. The strip is of the type having a top surface shaped to provide desired protective and/or decorative functions. The bottom surface is generally flat for bonding to a desired article such as a side panel or door of an automotive vehicle. In a preferred embodiment, the method comprises removing a V-shaped notch from the end of the strip, with the opening of the V at the end, to form adjacent triangular shaped legs. The notched end is then bent to stretch the bottom surface and the legs are drawn together to form the taper. The edges of the legs adjacent the taper are bonded together only at the pointed end. Multiple cuts are then made into the bottom surface of the strip, perpendicular to the line formed by closing the notch, between the tip and the original apex of the notch.

Abstract: A corner construction providing for planar deflection of a molding strip along its longitudinal axis. A V-shaped segment is removed along one side edge of the strip while a continuous band remains along the other edge. Portions are removed between the V-shaped segment and the continuous band whereby the strip can be deflected to permit a change in direction upon application to a mounting surface. The dimensions of the V-shaped segment and intermediate portions are selected to provide the strip with an uninterrupted corner of pleasing appearance having the desired angle of deflection.

Abstract: A small-lot bookbinding technique wherein a stack of collated paper sheets is held within a one-piece cover folder and adhered to the backbone thereof. The folder is constituted by a flexible panel having a pair of score lines defining a backbone zone flanked by front and rear cover sections. Fully coating the backbone zone and overlapping the score lines is a band of hot-melt adhesive material, the margins of the band slightly invading the cover sections, whereby when the paper stack is inserted within the folder with the edge thereof engaging the band and heat is thereafter applied to the band for a predetermined period, the adhesive melts and then, upon cooling, sets to firmly bond all sheets to the backbone including the first and last sheets of the stack.

Abstract: The disclosure is of a method of forming a mock selvage edge finish on a multi-ply, solid woven belting.

Abstract: In the production of a trim board such as an automobile roof trim board using a corrugated paperboard substrate which is bulged or dented in a comparatively small area and has an aperture in this area for the installation of a separate article, at least one linear notch is formed in a flat board of corrugated paperboard so as to extend transversal to the ridges of the corrugated medium and be entirely included in the area of the aperture as a preparatory procedure to press-forming of the corrugated paperboard. The presence of the notch allows some deformation of a tensioned liner also in the same direction as the ridges and hence precludes the appearance of cracks in the bulged or dented area. The notched region of the shaped board is thoroughly cut away as the result of the formation of the intended aperture.

Abstract: A water bed mattress comprised of upper and lower flexible foldable sheets which are essentially rectangular in shape. The upper sheet is essentially formed by folding up portions of the lower sheet upwardly and inwardly and transversely sealing end margins of the folded up portions, and also thereby creating two peripheral transversely extending side wall sections. In addition, longitudinal end portions of the upper and lower sheets are also folded downwardly and upwardly, respectively, and sealed to each other to thereby form longitudinally extending side wall sections, and which, together with the upper and lower sheets, create an internal water chamber. In the making of the water bed mattress, end cut-outs are formed in the sheets. Moreover, insert panels are heat-sealed to the interior portions of the side wall sections to cover these cut-outs and thereby seal the interior of the mattress.

Abstract: A method of assembling and embossing a multiple layer workpiece has, in a most complete conception, a first die having die surfaces for defining periphery of an area portion to be embossed on the workpiece which engages a blank to mark the blank with the die surfaces. Means are then located on the blank relative to the mark for operating on the blank to make a model of the desired workpiece from the blank. A second die is made conformably with the model. Workpiece layers are then assembled in overlapping relation and welded together by the first die along the periphery of the area porton defined by the die surfaces. Portions of one layer outside the welded periphery are then removed to leave the area portion covered by the one layer and secured to the other about the periphery of the area portion.

Abstract: Apparatus for manufacturing bolsters used to form the core for fabric windings includes apparatus to apply glue to specific areas of pre-sized cardboard cards, crimp the cards at specific locations to produce edges for the finished product, fold the crimped card, and compress the card to insure proper adhesion of the edges to the surfaces they contact, to form the finished bolster. The bolsters are produced by a method of passing a pre-sized cardboard card through the steps of gluing, crimping, folding and compressing, to provide a finished bolster of any predetermined length. A bolster is produced from a cardboard card of sufficient stiffness to provide for a substantially hollow construction, other than for a central stiffening spline used to determine the height of the bolster and provide rigidity to the bolster.

Abstract: A method of contouring a planar structure composed of a plastic layer sandwiched between opposing paper layers. A predetermined thickness of one of the paper layers is removed leaving a nappy contour layer surface. The nappy surface is then moistened. The moistened laminated structure is then bent to a predetermined radius of curvature and mounted in a fixture to hold the structure until it dries. Upon drying, the structure is removed from the fixture and maintains the predetermined radius of curvature.

Abstract: Improved forming method permits a flat laminate panel comprising a thin, deep vacuum formed thermoplastic face surface member bonded to a rigid backing member to be bent sharply so as to form the sides and front of a cabinet, for example, in one integral piece. The bends are accommodated by removing material from the back of the panel so as to form V-grooves whose included angles are equal to the angle of bends desired. The grooves extend through the entire thickness of the backing member and a portion of the plastic layer. A small bead of hot melt adhesive placed in the groove serves to soften the plastic so it can be bent without cracking. The panel sections adjacent the V-grooves are then brought into contact and immediately and permanently bonded together by the adhesive, thus eliminating the need for additional bracing while the adhesive sets.

Abstract: A method of fabricating a brassiere pad which involves folding a fiberfill blank longitudinally, making an oblique cut at right angles to the fold through one thickness of the blank, folding the blank so as to expose surfaces which are to be bonded, refolding to abut the surfaces to be bonded and molding the resulting form to the desired pad contour. Means for controlling the thickness of the under portion of the pad to provide desired push up action is disclosed.

Abstract: Plastic shutters and the like are manufactured by attaching a decorative plastic shroud to a supporting frame without substantial use of adhesives by a process in which a generally pan-shaped rectangular shroud is heat formed, the supporting frame is positioned within the plastic shroud, and the sides of the plastic shroud are post-formed to embrace the outer rim of the supporting frame. Since the supporting frame and the plastic shroud are not completely bonded to each other, the shroud and the frame can separately expand or contract without materially warping or distorting the shroud.
