In a method, at a draw frame for fibre slivers, of adjusting the nip line spacing of a drawing mechanism, which has at least two drawing mechanism roller combinations, of which at least one is so mounted that it can be adjusted, each drawing mechanism roller combination consists of at least one driven lower roller and at least one upper roller (press roller) lying, in operation, on top of the lower roller and so mounted that it can be lifted off. In order to allow optimisation of specific drawing mechanism settings using the same fibre material, with fibre slivers inserted, a) the upper rollers are unloaded or lifted off, b) the mountings of at least one lower roller are unlocked, c) the mountings are adjusted to the desired nip line spacing using a displacement device, d) the mountings are subsequently re-locked.
An apparatus at a draw frame having a drawing mechanism for the doubling and drafting of fibre slivers, having a drawing mechanism frame for accommodating the drawing mechanism, which has at least two pairs of rollers each comprising an upper roller and a lower roller, having means for adjusting the spacing of a least one of the lower rollers in relation to another lower roller, in each case having a mounting device for accommodating the lower roller, wherein lower rollers are arranged to be driven by at least one drive element endlessly revolving around pulley wheels, wherein at least one pulley wheel and the tensioned drive element are used for adjusting the mounting device wherein a moving force applied to the pulley wheel or to the drive element can be converted into the adjusting movement for the mounting device.
The apparatus according to claim wherein a roller-driving pulley wheel and a guide pulley wheel are attached to a slider of an intake roller and a roller-driving pulley wheel and a guide pulley wheel are attached to a slider of a middle roller.
A method for adjusting nip line spacing in a drawing mechanism of a draw frame for fibre slivers, the drawing mechanism including at least two adjustable mounting devices defining a nip line spacing therebetween, each mounting device including at least one lower roller and at least one upper roller adjustably loaded on top of the lower roller, and at least one of the at least two mounting devices including a pulley wheel in driving connection with a driving element, the method comprising:
An adjustable drawing mechanism in a draw from for fibre slivers, the adjustable drawing mechanism comprising:
