Abstract

The invention relates to an injector head (2) comprising; a pair of oppositely located, cooperatively movable, segmented continuous belt drive chains (21; 22), said each belt drive chain (21, 22) running over a respective pair of drive sprockets (25a, 25b) and tension sprockets (26a, 26b), wherein a tubing receiving section (7') is defined between the belt drive chains (21, 22). The tubing receiving section (7') having a tubing section centerline (46) extending through the center of the tubing receiving section (7'). The injector head (2) having an injector centerline (45) extending through the centerline of the injector head (2),said injector centerline (45) and said tubing section centerline (46) being substantially aligned in the longitudinal direction in an initial position, a pair of elongate counter-force members (32a, 32b) is positioned at each side of the tubing receiving section(7'). The injector head (2) has at least one actuator (35) adapted to move at least one of said elongate counter-force elongate member (32a, 32b) in order to bring the tubing section centerline (46) out of alignment with said injector centerline (45).
