Abstract
Electromotor driven tensioning and winding device for lashing straps (7) in integral construction, preferably including a tactile three-point measurement sensor (2) in direct contact with a flat side (40) of the lashing strap (7). For this purpose, the measurement sensor (2) includes a sensor bar (30) which is mounted against a compression spring element (31) and has a contact pin (34) which is movable together with the sensor bar (30) and can be pressed against a contact plate (37) fastened to the rear wall (32) of the measurement sensor housing (27). If the desired tension of the lashing strap is reached, the contact pin (34) lies against the contact plate (37). If the contact between the contact plate (37) and the contact pin (34) is interrupted, the drive motor (3) receives a signal to tighten the lashing strap (7) by further winding it onto the wind-up spindle (6). The desired lashing tension of the lashing strap (7) is thus regulated continuously.
