摘要

Improvements in the construction of paraframes in the looms, characterized by the fact that in order that the loom of the loom is produced automatically and immediately after the break of the thread of the weft, it remains in constant tension which determines a position previously calculated, of a reflective, oscillating sheet, located in the shuttle or other convenient part of the machine, so that the light rays of a light source facing said reflective plate, do not impinge with the photoelectric cell of the circuit, being reflected, and only if, when pro breaking the thread or other cause, the tension existing in it ceases, with which the elastic means to which the reflective sheet is linked, by virtue of disappearing the aforementioned antagonistic tension of the thread that expired to that of the elastic means arranged, allows them to act, then, freely, and vary the angular position of the so repeated lamp. Ina, so that in this way the light rays are reflected, then, against the appropriate photoelectric cell that commands the operation or stoppage of the loom.
