Abstract: A method for the three-dimensional forming of an upper of a footwear, comprises: preparing a sock comprising thermoplastic yarns; fitting the sock on a reference form of an upper to be formed; placing the reference form with the sock in an oven; heating the sock in the oven up to determining the at least partial fusion of thermoplastic material of the thermoplastic yarns of the sock; cooling the sock up to determining the cross-linking of the thermoplastic material and the formation of the upper with more rigid portions and less rigid portions; removing the upper from the reference form.

Abstract: Described are methods, systems, and devices for at least partly manufacturing a piece of apparel (e.g., a shoe), which incorporate manipulating at least one component of the piece of apparel with a particle jamming device.

Abstract: A floor scrubber machine can comprise a chassis, a scrub deck and a propulsion system. The scrub deck can include a hands-free, double-scrub side skirt mechanism, and a dual mode side blade assembly. The chassis can include a rear squeegee assembly having a self-aligning hanger system with balanced handles. The propulsion system can include a throttle pedal having a button for forward/reverse control, and a control panel having a setting for rescaling the acceleration profile. A disc brush scrub deck can include a brush centering mechanism. A cylindrical brush scrub deck can include an idler end brush cover with self-aligning tabs, and a self-contained drive mechanism.

Abstract: A shoe support for supporting a shoe, bottom uppermost, with the bottom thereof exposed for an operation to be performed thereon, has a heel end support arrangement and toe end support means moveable relative thereto to accommodate shoes of different sizes. Associated with the toe end support means is a "shoe present" sensing device which, when actuated, initiates movement of the toe and support means. The shoe support also has a shoe length sensing device and an arrangement, associated with the heel and support arrangement and including an inductance sensor, for sensing whether the shoe is a left or right.

Abstract: The machine comprises a shoe support (20) on which a shoe can be positioned, and which includes a toe end engaging member (48) which senses the shoe length, two abutment faces (84, 90) being set along shoe length sensed. The machine also comprises adhesive-applying nozzles (262) and side lasting rolls (224) mounted on a carriage (216) for movement relative to the last support. The "start" position of the nozzles is set by valves (334,336) actuated by cams (330, 332) positioned by a sensing member (326) engaging with one abutment face (84). Various other machine operations, which take place at the ball region of the shoe bottom, the position of which region thus varies proportionately with shoe length, are controlled by further valves (354, 356) actuated by cams (350, 352) carried on a control rod (344) the position of which is determined by a sensing member (338) engaging the other abutment face (90), an appropriate length grading arrangement (342) connecting said member and said control rod.

Abstract: A shoe support comprises toe support means (34) and heel support means (30), the toe support means being mounted for adjusting movement relative to the heel support means in directions extending lengthwise, widthwise and heightwise of the bottom of a shoe supported by the shoe support. The heel support means (30) comprises a last pin (32') mounted for limited rocking movement abut an axis (412) extending lengthwise of the shoe bottom, the last pin being supported on a support member (420) which is angularly displaceable on a support rod (28), the arrangement being such that the rocking axis (412) of the last pin (32') can be adjusted angularly on the support rod, thus to locate said axis (412) substantially in the heel-to-toe plane of the shoe, as determined by the position of the toe support means (34). In this way, the shoe is supported in a more stable manner for operations to be performed thereon, e.g. a heel seat lasting operation.

Abstract: In tack seat lasting machines, operator skill is often required because of irregularities in last manufacture, especially in drilling the last pin hole. Thus, automatic presentation is difficult. In accordance with the invention the last pin (32') is mounted for limited rocking movement about an axis extending lengthwise of the shoe bottom, and shoe centralizing means (424) engages edges of the shoe, at opposite sides of the last pin, to ensure alignment with a longitudinal center line of the machine. The centralized shoe is then clamped by a holddown (406), the centralizing means released, and the shoe heel end clamped by a heel band (520) which, by equalized pressure being applied to both "legs" thereof, holds, the shoe in position as presented.

Abstract: Size numbers of shoe lasts fixed on heel supports on shoe manufacturing machines are determined by electrical circuits comprising photocells which check the distance between the toe and heel of the last, said electrical circuit controlling the position of form plates for the adjustment of elements which work upon shoes on the shoe manufacturing machines.

Abstract: A device for use in the manufacture of shoes in which the shoe is mounted on a last while being machined. The last is tiltably supported near the heel end while a longitudinally adjustable tip support member supports the tip end of the last. A guide member near the tip support member guides a tool during the machining of the shoe. Adjustment of the tip support member longitudinally to adapt the machine to different lasts is accompanied by adjustment of the tip support member and the guide member respective amounts in a direction perpendicular to the longitudinal direction of the last.
