Abstract: An electronic system for controlling the operation of a hand-held pull strap closure unit. The system includes a central processing unit which controls peripheral circuitry for directing commands to a motor within the hand-held unit. The system further includes a circuit for monitoring motor torque and a hand-held unit identification circuit for identifying each unit with an individualized code. The CPU may be accessed via an external communications port to store user-selected operational parameters in a memory circuit. These parameters may include time of day, calendar, and motor torque limits for each device.

Abstract: A fastening device for heating plates of a heating device of a corrugated board plant. Each heating plate is fastened on a form-stiff and fixed frame. The ends of the heating plates are supported by loose support devices. Thus, a flat heating surface for the strip of corrugated board guided over the heating surface is maintained even during a limited expansion of the heating plates due to the effect of heat.
