Abstract
Machine for preforming shoe uppers of the kind of those in which the periphery of the upper is squeezed between two surfaces during the action of a mold reproducing the profile of the last on which the shoe will be mounted, characterized in that the mold is articulated by one of its ends about an axis fixed in relation to the frame of the machine, and in that said mold can be displaced in a direction at right angles to the axis of rotation of the lever supporting it.
Claims9
In a machine for preforming shoe uppers, in combination, a mold, a frame, a lever articulated on said frame and supporting said mold, a notched platform being supported under said mold, a notched plate being supported under said platform and on which the upper to be formed is to be positioned, a movable box supporting said plate, an elastically deformable member being positioned in the center of said box, means capable of pivoting said lever and causing said mold to pivot through the notches in said platform and said plate and means capable of displacing said box towards said plate.
In a machine for preforming shoe uppers, in combination, a frame, a lever articulated on said frame and supporting a mold, a member interposed between said lever and said mold to displace the mold independently of said lever in a direction at right angles to the axis of rotation of said lever, a notched platform under said mold, a notched plate under said platform on which the upper rests, a movable box as support of said plate, an elastically deformable member in the center of said box, and means for causing said lever to pivot and for displacing said box.
