  • Patent number: 5678269
    Abstract: A machine for lasting the toe and side and heel of an upper to an insole mounted to a last includes a toe and ball wiper assembly and a heel and shank wiper assembly in combination with a pincer assembly mechanism for stretching the upper tightly about the last and a toe clamping mechanism for clamping the stretched upper against the last. Following stretching and clamping, the toe wipers are actuated to press the upper margins against the insole bottom against the counter force of an overhead toe hold-down acting against the top of the upper. A brake mechanism fixes the overhead hold-down to maintain the toe wiping plane in a constant position. The heel wiper assembly is elevated within the machine to locate the heel wiper plane at a proper height relative to the insole bottom, the proper height being determined with a sensor mounted for movement with the heel wiper assembly. A heel clamping pad assembly connected to the heel wiper assembly then clamps the heel prior to stretching of the upper.

  • Patent number: 5659914
    Abstract: A method for construction of waterproof footwear includes providing an upper defining an internal volume for receiving and protecting a wearer's foot against external elements, lasting and securing an inner liner having a waterproofing layer within the internal volume of the upper, securing the inner liner at a lasting edge portion of the liner to an insole having an external surface, securing a gasket element over the lasting edge portion of the liner and external surface of the insole, lasting the upper over the inner liner, and securing an outsole to the lasted upper. Performing two independent lasting operations ensures that during use, even if water somehow penetrates the upper, the lasted inner lining provides independent protection to the wearer's foot.

  • Patent number: 4654914
    Abstract: A side and heel lasting machine that serves to adhere the upstanding unwiped side and heel margin of a shoe upper assembly, which assembly includes a last with an insole on the last bottom and an upper draped about the last. The toe portion of the upper assembly has previously been wiped to the periphery region of the assembly insole. A pair of pincers, one disposed at each side of the upper of the assembly, grasps the upstanding unwiped margin and draws it upwardly, inwardly and forwardly (i.e., towards the toe thereof) to fit it snugly about the last. Lasting pads are employed to keep the unwiped margin in position during application of adhesive from nozzles that are spring loaded to press outwardly and track the upstanding unwiped margin when adhesive is applied in the region between the insole and the margin. The upstanding side and heel margin is then wiped onto the insole.

  • Patent number: 4602398
    Abstract: A machine for lasting the heel of a shoe comprising a shoe last support including an axially displaceable column having a free end. The support is displaceable from a first retracted position to an advanced position and a shoe last is mounted on the free end of the column for limited rocking movement relative thereto to permit realignment of the shoe last. The column may be elevated from a lower position, and when so elevated, strikes the inner edge portion of the heel band wiper plate which has been displaced to a selected position in interference with an edge portion of the shoe last. Such upward movement of the shoe last will be, accordingly, stopped by the interfering edge portion of the heel band wiper plate and the shoe last will be automatically aligned into uniform engagement therewith. The column is locked at the stopped position and a heel band forcefully engages the stopped and aligned shoe last to maintain the shoe last at that position in that alignment.

  • Patent number: 4593423
    Abstract: In a combined heel seat and side lasting machine, in which the heel seat lasting operation takes place during the dwell time necessary for the cement side lasting operation, the backpart of the shoe remains free of any clamping pressure at least in and adjacent the backseam region thereof, which pressure would have the effect of forcing excess material out of the heel seat region into the region to be lasted by the side lasting instrumentalities, while at the same time provision is made for locating the shoe, prior to the side lasting operation, in a predetermined relationship, both heightwise and lengthwise, with the heel seat lasting instrumentalities. To this end, the shoe is first located lengthwise by the heel band (16), whereafter, with the shoe clamped against a holddown (20), the heel band is retracted out of engagement with the backseam region of the shoe during the side lasting operation.

  • Patent number: 4573229
    Abstract: A machine for lasting sides and heels of a shoe assembly having a last with an upper mounted thereon and an insole at its bottom, the assembly being one whose toe portion has already been wiped and whose side and heel portions are to be wiped. Nozzles serve to apply adhesive as a ribbon into the region between the insole and the unwiped margin at and near the insole periphery. A lasting mechanism provides backup to the margin to permit the nozzles to press outwardly against and track the margin. Later the lasting mechanism applies inward and downward pressure onto the margin. The lasting mechanism includes a lasting instrumentality at each side of the shoe assembly. Each such instrumentality includes an inner, an intermediate and an outer flexible lasting pad; each pad has relatively rigid segmets at its top edge; and each is moved by air cyliers to perform its function. The inner lasting pad performs a backup function during application of adhesive and a wiping function.
