Abstract (en)

[origin: EP3231905A1] A device (1) for the INTERRUPTING of the feed of a roving (12) when breakage of a filament (11) occurs during the process of spinning core yarn, characterised in that it comprises a wedge (2) arranged to be inserted, in its active position, between a pair of roving (12) feed rollers (6a, 6b), said wedge (2) enabling the INTERRUPTING of the feed of the roving (12) by acting on said rollers (6a, 6b); said device (1) featuring a mechanism (3, 4, 5, 7) to activate the displacement of the wedge (2) towards said active position when the breakage occurs. A procedure for the INTERRUPTING of the feed of a roving (12) when breakage of a filament (11) occurs during the process of spinning core yarn, comprising the stage of separating the roving (12) feed rollers (6a, 6b) by strictly mechanical means (2) to grasp the roving (12) and to halt its feed when a breakage of the filament (11) occurs.
