ABSTRACT:
A device for breaking off edge strips from a blank, within which model glass sheets of present shape are scratched. The breaking off edge operation takes place with the aid of pressure pins, placed on a carrier plate arranged parallel to glass sheets. The pressure pins are adapted to be lowered onto the edge strips which are to be broken off. The plurality of pressure pins are located on the carrier plate in a broad arrangement covering various sizes and shapes of the glass sheets. Each individual pressure pin, independently of the neighboring pressure pins can be moved from its retracted rest position into its lowered working position as a function of the shape and size of the respective glass sheet. The pressure pins may be operated by pneumatic cylinders controlled in accordance with a program allocated in each case to the glass sheet to be processed. The invention permits control of a breaking off device for molded glass sheets according to a preset program. The device may be used in the application of locally acting pressure forces on a glass sheet, such as auto glass sheets within a production line.
