Abstract
A stitcher (1) for connecting strips of rubber material (4, 5) into a substantially continuous strip according to this invention comprises a surface (3), a stitching head (6) placed over it having a stitch unit (7) for stitching the strips of rubber material together along a stitch line, which stitch line includes an angle α having a longitudinal direction (L) of the continuous strip, a drive mechanism for driving a relative movement of the stitching head with respect to the surface along a first (X) and a second (Y) direction, wherein the second direction is oriented transverse to the first direction, and a control device (11) for controlling the drive mechanism such that the stitch unit follows the stitch line. In one embodiment the stitching head is rotatably connected to the drive mechanism wherein the axis of rotation extends transverse to the surface. The stitching head furthermore comprises a wheel (15) that is placed at a distance from the axis of rotation, wherein the wheel with its tread abuts the surface.
