Abstract

Abstract An upper taping head is fixed to a vertically movable cross-piece whose ends are engaged in two fixed support and guide columns. To adjust the position of the cross-piece, there is provided at least one threaded rod borne in a rotating manner by one end of the cross-piece and engaged in a nut screw which is fastened to the corresponding fixed column. A control crank may be placed on the top of the threaded rod or shifted toward the center-line of the cross-piece and connected to the cross-piece by a transmission chain borne by the cross-piece. A second threaded rod may be provided for the other end of the movable cross-piece and connected by a transmission chain borne by the cross-piece to the first rod and to a control crank shifted toward the center-line of the column.
