Via a keypad strip 15 different crimping values and 16 intermediate values can be selected. A knee switch turns them on and off again. In order to achieve a securer d raw i ng of the stitches a second needl e thread tension is switched on when a crimping value is turned on. The moment of swi t c hi n g o n a s eco nd needle thread te ns ion can be preselected between crimping values 1 and 5 inclusive.
