Abstract
A guide template for sewing machines in which a driven roller follows along the template's contour to sew workpieces of different form and/or size. The template has a number of sections which are movable relative to one another. For purposes of lengthening one of these template sections, a second movable and adjustable template section is provided in combination with a third template section which is pivotably mounted on the second template section. The third template section may be adjusted to different contours by an adjustment device. This adjustment device has a cam plate interacting with the third template section, and mounted rotatably on the machine frame through the use of a handwheel. The second template section is located between the first and third template sections, and is used to extend the template. The second template section is held by a gear rack on a plate on the machine frame, and the gear rack engages a pinion which is rotatable with an adjustment knob for shifting on the gear rack. The plate holding the gear rack has slotted holes for shifting the gear rack and the second template section.
