Abstract

A supporting welding plate for the spot welding of a steel tape binding together a plurality of longitudinal objects, the plate supported on a pivotable lever, thus enabling its lateral removal after finished welding and thus enabling a free manipulation with the formed packet of bound objects without any danger of damaging the formed hoop or the welding plate.

Claims

1. In a binding machine for binding together a plurality of objeCts with a loop of a metal tape connected by spot welding to form a bundle, said binding machine including a machine frame having object supporting means thereon, guide means operatively mounted in said frame for guiding a metal tape in a loop around said plurality of objects on the supporting means on the frame, and means for spot welding together overlapping portions of the tape loop, the improvement which comprises:

a welding support plate on the frame selectively movable from an operative position in which it lies within a loop of tape and underlies and forms a support for the objects to an inoperative position laterally removed from the loop, said welding support plate in operative position overlying overlapped portions of the tape and forming as a first electrode, a second electrode selectively movable from an operative position in which the overlapping portions of the tape are gripped between it and the welding support plate to an inoperative position spaced from the tape, a second said welding support plate electrode mounted on one end of a pivotable lever, a pivot pin on the frame supporting the other end of said lever, the longitudinal axis of said pivot pin being parallel with the plane of the loop passed around the bound objects, and means for selectively swinging said lever to move the support plate into operative and inoperative positions.

2. A binding machine as in claim 1, wherein said means for selectively swinging said lever to move the support plate into operative and inoperative positions comprises a power cylinder having a piston rod, the power cylinder being pivotally supported on the machine frame, and the outer free end of the piston rod being pivotally connected to the lever.

3. A binding machine as in claim 1, wherein the second electrode is moved toward and away from the support plate in a direction normal to the broad extent of such plate, and comprising power means for moving the second electrode.

4. A binding machine as in claim 3, wherein the means for moving a second electrode includes a second power cylinder, the second cylinder having a second piston rod, the longitudinal axis of the second power cylinder and the second piston rod lying in the plane of the longitudinal axis of said pivot pin which pivotally supports the first power cylinder on the frame.
