摘要

The invention refers to a quick-opening door comprising: a flexible canvas secured to a motor-driven drum and provided with vertically aligned arrangements of abutment elements that are guided in vertical uprights of the door; an electric duct secured to one of the sides of the canvas and provided with cables connected to a wireless signal transmitter; a plurality of guiding abutment elements distributed along the sides of the canvas with different spaces there between, disposed either singly or in groups; sensors which are disposed in an abutment passage zone and which capture different sequences of pulses during the passage of the abutment elements, thereby determining the position of the canvas at all times; and a contact-detecting band connected to the transmitter via the electric duct and housed in a bag by means of which the canvas is fitted against the ground.
