2 Claims. (Cl. 164-124) This invention relates to punch devices and body of the device in a heat insulating body i0. more particularly to punches for formingholes Electrical energy is supplied to the resistance in semi-plastic sheet material such as unvulwire 8 by the lead-in cord ll. canized rubber and the like. In operation, the cutting edge 2 of the punch An object of the present invention is to provide l, is caused to pass down substantially through a punch that is particularly adapted for conthe uncured side wall rubber [2 of the inner tube ventional practices in the manufacture of rubber while supported on the bench l3. The notch 3 inner tubes. in the cutting edge 2, leaves a connecting ribbon Another object is to provide a punch that M of the stock that anchors the cut-out slug 15 leaves the punched-out slug free of the punch to the material of the tube wall. The major 10 cutting blade and somewhat elevated above the portion of the slug I5 is drawn up out of, and material punched in order that the slug may be inclined to the plane of the tube wall I2 when the readily grasped and torn loose by the punch oppunch is lifted, as shown in Fig. 4. The slug [5 in erator. its elevated and inclined position is easily and With the above and other object in view, quickly grasped by a worker and the ribbon I4 which will be apparent to those familiar with broken to complete the operation. This avoids the art to which this invention pertains, an emthe use of complicated means for clearing the bodiment of the present invention is disclosed in punch cavity and is very convenient and useful in the accompanying drawing, wherein operation.

Figure l is an elevational View, shown partly It is to be understood that the particular emin section with parts broken away, of a punch bodiment of the invention that is shown and assembly that embodies the present invention; described herein is for the purposes of illustration Fig. 2 is an end view of the punch blade lookand explanation and that various modifications ing in the direction of the arrows 22 of Fig. 1; in the punch and in the contour of the punch Fig. 3 is an enlarged elevational view in section cutting blade and notch, and in the carrying and g of the punch blade in an operating position in supporting means, and in the punch heating the process of punching openings for valve stems means, may be made without departing from the in an uncured rubber tube wall; invention as defined in the appended claims.
