Abstract
In a heel seat lasting machine (or combined side and seat lasting machine) the shoe is located lengthwise and heightwise in relation to the heel seat lasting instrumentalities (18) by first locating it lengthwise by the heel band (16), retracting it through a predetermined distance to separate it from the heel band, locating it heightwise against a holddown (20), and returning it to its lengthwise location, moving the holddown therewith during the return movement.
Claims12
A machine for lasting heel seat portions of shoes comprising:
- a shoe support, for supporting a shoe comprising an upper and an insole carried on a last,
- a support head on which are mounted a heel band,
- a holddown and heel seat lasting intrumentalities comprising:
- two wiper plates, means for effecting relative movement of approach between the shoe support and the support head to bring them to an operative relationship determined by engagement of the heel end of a shoe supported by the shoe support with the heel band, the shoe thus being located in a lengthwise direction relative to the heel seat lasting instrumentalities and to the holddown, and means for effecting relative heightwise movement between the shoe support and the holddown, whereby to locate the heel seat region of the shoe bottom in a heightwise direction relative to the plane of the wiper plates of said instrumentalities, wherein means is provided, operable when the shoe support and support head are in their operative relationship, for effecting relative movement of separation between the shoe support and heel band through a predetermined distance to disengage the heel end of the shoe from the heel band, the relative heightwise movement between the shoe support and the holddown taking place while the heel end of the shoe and heel band are thus disengaged, whereafter return movement is caused to take place between the shoe support and the heel band to return the heel end of the shoe into engagement with the heel band.

A machine for lasting heel seat portions of shoes comprising:
- a shoe support, for supporting, bottom uppermost, a shoe comprising an upper on a last with an insole on the last bottom;
- heel seat lasting instrumentalities;
- a heel band, which serves to determine the position of a shoe supported by the shoe support, lengthwise of its bottom, in relation to the heel seat lasting instrumentalities and to clamp the heel end of such shoe thus positioned;
- a holddown, which serves to determine the heightwise position of a shoe supported by the shoe support in relation to said instrumentalities, and between which and the shoe support such shoe can be clamped thus positioned;
- first means for moving the shoe support inwardly towards the heel band, in a direction extending generally lengthwise of the bottom of a shoe supported by the shoe support, and second means for effecting relative heightwise movement between the shoe support and the holddown;
- the arrangement being such that a shoe positioned and clamped on the shoe support as aforesaid in relation to the heel seat lasting instrumentalities can then be operated upon thereby,
- wherein the holddown is movable relative to the heel band in a direction extending lengthwise of the bottom of a shoe supported by the shoe support, as relative movement takes place between the shoe support and heel band under the action of said first means.
