Abstract: A multi-station machine for marginal roughing and toe scouring of shoe bottoms has a turret arrangement, carrying a plurality of shoe supports. At a marginal roughing station two rotary roughing tools operate along opposite marginal portions, during movement of the tools lengthwise of the shoe bottom respectively in a first and a return direction, the shoe support being movable heightwise and widthwise of the shoe bottom so that each tool follows the shoe bottom margin contour. The tools can also pivot about a horizontal axis to maintain their plane normal to the shoe bottom portion being operated upon. In-machine brush grinding is provided, using rotating stones, the speed of rotation being about twice that of the roughing brushes, and the direction of rotation such that the peripheries of stone and brush, at the point of contact, move in the same direction.

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.
