@The upper-trimming device a 29 comprises a middle knife 66 (Figsifi and 8) which is curved in general similarity to the curvature of the edge or the insole around" the end of the toe and is movable lengthwise of the shoe toward the toeend gripper l2, and two sid'eknivestii movable laterally of the shoeltowardthe side grippers It 7 in paths curved about a vertical axis located opposite the end of the toe. The-cutting edges of theseveral knives,j-in operating on theupper,

move in a plane parallel to the top faces of the Wipersand. spaced from these faces-a distancesubstantially equal tothe thickness of the outer layer of the uppermaterials, so that as the mar ginal portion of the different layers areoutturned overthe wipers the knives sever the surplus marginal material of the inner layer or layers ,while'leaving a margin of the outer layer to be lasted inwardly over the insole. As illustrated, the top faces of' the wipers (Fig. 7) are positioned at the-,time of the upper-trimming operation somewhat above thejplane of the bottom "face of the toe end' of -the insole, to leave enough {of the inner *layer-or layers to overlap the extrememarginal edge of the ins'olewhen thefwip'ers thereafterwipe the louter layer in wardly. It will be understood that thetoe end of the upper materials usually comprises at least three'layers; including a liningand a toe. box in addition to the outer layerybut' for convenience ol illustration the drawings show onlythe lining in addition to the outerlayer: As shown in Fig. 8, the shoe isfpreferably prepared for the operationof the machine byslitting the margin of the upper materials at the sides of the toe I forwardly of the side milling-overtacks, to facilif tate turningoi the margin of the toe-end por tion of the materials outwardly'in parallel relaor tion to the pla'neof the WiperS and the knives act to sever completelythe surplus margin of the inner layer orlayers from the rest of the up perjrnaterlals'.
