Abstract: A method for manufacturing a shoe, which includes the steps of:arranging an upper-insole assembly about a last;coupling an intermediate member comprising a toe portion and a heel portion to a lower region of the upper-insole assembly arranged about the last; andarranging the intermediate member in a mold and introducing plastic material into the mold so as to form an injected plastic material member which surrounds the intermediate member and which is integrally connected with both the intermediate member and the upper-insole assembly.
Abstract: An apparatus and methods are provided for treating a workpiece such as a shoe component. The workpiece treating apparatus preferably includes a transporter for transporting a workpiece along a predetermined path of travel and a storage device for storing a plurality of predetermined parameters of each of a plurality of workpieces. A workpiece identifier is positioned responsive to the storage device for identifying the workpiece during travel along the predetermined path. A workpiece treatment applicator is positioned adjacent the transporter and responsive to the workpiece identifier for applying a treatment a workpiece being transported along the predetermined path of travel. A workpiece treatment position determiner preferably is positioned responsive to the workpiece identifier for continuously determining the position of the workpiece treatment applicator along a predetermined trajectory during treatment of the workpiece.

Abstract: A method for applying glue to the upper surface of soles for footwear includes the steps of transferring a sole to a first station with the upper surface turned upward, picking up the outline of the sole, transferring the sole from the first station to a second station, keeping the sole orientation unvaried and applying a jet of glue directed to the upper surface of the sole along a path that can be adjusted and that follows the border of the sole. In a different embodiment, glue is also applied to the surface of the upper that is intended for attaching of the sole.
Abstract: A waterproof article of manufacture and method of manufacturing the same including a waterproof, breathable shell and an aqueous based waterproof sealant disposed on the shell adjacent seams used to assemble the shell into an article. The article may be a lining for footwear.
Abstract: In order to produce a shoe without insole, the lasting fold of a shoe upper (4) is glued directly on the underside of a last (1), specifically with the use of an adhesive which is selectably releasable at some later time. Next, an outside sole (5), which is provided with an adhesive layer (6) in the area of the lasting fold and possibly in the area of the side leather, is glued to the shoe upper (4). Next, the adhesive power of the selectably releasable adhesive is cancelled, for example, by means of heating, and the adhesive power of the adhesive (6) between the shoe upper (4) and the outside sole (5) is increased. Now the last (1) can be removed from the completed shoe. Such a shoe without insole is particuarly suited as an orthopedic shoe which makes possible a direct contact between the foot and the soft upperside of the outside sole (5).
Abstract: This invention relates to new, substantially linear polyester polyurethanes containing hydroxyl end groups, based on selected starting materials, and their use as adhesives or for the production of adhesives.

Abstract: A method of making shoes of the type having a soft sole and an insole part used in the method. The insole part is produced by cementing a thin and soft insole sheet on a hard insole base so as to be easily peeled apart an separated. The method includes using the insole part in lieu of a conventional insole, performing a conventional lasting manufacturing method, separating the insole base from the insole sheet and leaving only the insole sheet. A highly efficient manufacturing method is thus provided by using a lasting machine.
Abstract: Method of bonding a sole to a shoe by applying moisture-curable melt adhesive to the shoe upper, subjecting the adhesive coating to a hot-cure step with airborne moisture, and pressing the sole and shoe upper together with the adhesive between them immediately after the hot-cure step, preferably in less than 90 seconds after leaving the hot-cure. The bond is effected without application of adhesive to the sole, which is merely pre-treated by wiping with solvent or primer solution.

Abstract: In a method for producing footwear, wherein the shaft and the shell sole of the footwear are glued together, the leather upper part of the footwear is first cut to size without the formation of a lasting fold, it is prepared and then roughened along a lower border thereof. After shaping of the tip, so as to conform to the last, the preformed shaft is stretched to measure, and a rear cap is simultaneously molded in. The shell sole, which is likewise glued, is placed on a glued border and pressed against at least the tip and heel and is also possibly sewn with a seam, after which a cover sole is placed and the shoe or footwear is completed.
Abstract: A shoe is provided having a soft, and compliant insole and a cushioned outsole. In manufacturing the shoe, the insole is temporarily stiffened by a relatively firm member to which it is bonded by means of a wax. This enables the insole to withstand the normal lasting procedure. The outsole is provided with a cavity for receiving a cushion therein. The shoe upper is attached to the outsole such that the insole overlies the cushion. Once the shoe is completed, the wax bond between the insole and its stiffener is heated to allow the separation and removal of the latter.
Abstract: Clog-type shoes are produced by combining foamed polymeric soles with conventional vamps by interposing selected adhesives and application of pressure and heat to the assembled clog-type shoe.
Abstract: A waterproof hip length boot and method of manufacture wherein the fabric lined upper leg portion is attached as a sheet around its lower edge to the upper edge of the lower boot portion by an adhesive such as urethane or another synthetic polymeric material having similar properties that provides circumferential and longitudinal bonded seams and also coats the fabric opposite the wearer's knee for internal abrasion protection.
Abstract: Process and apparatus for applying adhesive to a surface and for bonding and particularly for attaching a tread member to a shoe in which an adhesive applicator including a jet providing a gas stream having a rotational component is constructed to extrude viscous fluid adhesive to form a filament and to lay down the filament while still soft and adhesive as a band of overlapping loops directly on the attaching surface of an element to be adhered. The elements to be joined are pressed together with the adhesive between them and the adhesive is hardened.
