ABSTRACT:
A template control for relative movement between a workpiece or material and a tool which may be in the form of a needle on processing machines. The template is adjustable to different shape and/or size of a workpiece which may be in the form of a garment. A roller is pressed against the template which is provided with a coaxially located and driven gear pinion. The pinion meshes with teeth adaptable to the shape of the template for purposes of guiding the roller without slippage along the template. The latter has an elastic tape which determines the shape of the contour. The tape is held in a number of tape carriers arranged displaceably next to one another and parallel to one another. Displaceable tooth segments under tension of a spring, are associated with the tape carriers. These tooth segments when located next to one another, form a gear rack with identical toothing. The template may have a large number of segments which are displaceable relative to one another and carry the track for the segments pressed against the roller. Each of the segments is assigned to one tooth segment which is under the tension of the spring and is displaceable relative to the segments.
