Abstract
A machine that molds an upper to the shape of a male mold by a female mold and that flanges the margin of the upper by a pair of wipers mounted to the female mold. The wipers have bases hinged to each other for swinging movement about a vertex and legs extending forwardly and divergently of the bases, the wiper bases being mounted to a back part of the female mold and the wiper legs being mounted to side parts of the female mold. The wiper bases are so constructed as to be movable forwardly of the back part and the wiper legs are so constructed as to be movable inwardly of the side parts pursuant to the forward movement of the wiper bases relative to the back part.
Claims2
An upper molding and flanging machine comprising:
- a male mold;
- a female mold mounted for forward-rearward movement towards and away from the male mold, the female mold having a back part and side parts extending forwardly of the back part and mounted for inward-outward movement with respect to the back part;
- a pair of wipers having bases hinged to each other for swinging movement about a vertex and legs extending and divergently of the bases, the wiper bases being mounted to the back part and the wiper legs being mounted to the side parts;
- means for initially maintaining the female mold in a rearward position spaced from the male mold with the side parts and the wiper legs in outer positions;
- and means for thereafter imparting forward translatory movement to the female mold to cause the back part to press the back end of an upper mounted on the male mold against the back end of the male mold, said pressing of the back end of the upper against the back end of the male mold terminating said forward translatory movement, and for then causing the side parts to move inwardly and press side portions of the upper against the sides of the male mold;
- characterized in that the machine comprises:
- means mounting the wiper bases to the back part for forward-rearward movement;
- means for initially retaining the wiper bases in a rearward position relative to the back part;
- and means effective after the termination of the forward translatory movement of the female mold for moving the wiper bases forwardly with respect to the back part, the mounting of the wiper legs to the side parts being so constructed and arranged as to cause inward movement of the wiper legs about the vertex in response to said forward movement of the wiper bases.
