ABSTRACT:
A rolling-up machine for lengths of cloth destined for collar-cutting machines, comprising a rolling-up bar, motor to drive the bar, a cloth-drawing roll, motor to drive the roll, a mobile frame carrying fixed stretching bars and a bar carrying the cloth to be rolled up, the mobile frame being able to move transversally to the direction of unrolling of the cloth and continuously align the profile of one of the edges of the cloth roll corresponding to the head of the roll formed on the rolling-up bar, a cloth-stretching roll spaced from and parallel to the cloth-drawing roll and rotating in the same direction; a pair of idler bars seated below the stretching roll on the mobile frame; these idler rolls being pressed one against the other so as to press the cloth passing therethrough and cause a relative transverse sliding motion between the stretching roll and the cloth as a result of the movement of the mobile frame in response to variations of the width of the cloth as detected by sensitive means, the interaction of the stretching roll with the pair of idler bars being capable of cancelling any undulation in the cloth and maintaining the edge of the cloth perfectly straight and well aligned with the feed path.
