Abstract
A device for the roll-up of blinds or the like that has a tubular motor mounted in a roller tube. An automatic stop and a detector for detecting that the motor is blocked, causing the motor to be stopped. The automatic stop has a screw carrying a traveling nut restrained against rotation in a tubular housing. The motor is stopped by detecting blockage of the motor through the traveling nut or the end of a blind or the like coming against a stop. Adjustment is carried out by manually rotating the housing via the housing end cheek.
