Device on a spinning preparation machine, in particular carding machine or carding machine, in which the fitting of a roll, for example, drum, at least a garnished and / or nichtgarniertes, stationary machine element opposite at a distance.

摘要

In a device on a spinning preparation machine, in particular carding, carding, in which the clothing of a roller, e.g. Drum (4), at least one garnished and / or ungarnished, stationary machine element at a distance (a) opposite, end portions of the machine element (17, 23) bearing surfaces, with the bearing surfaces of stationary supports (19a, 19b) in each case stand. In the area of the end parts or the supports, in each case an adjustment means is arranged which is able to change the radial distance between the clothing of the roller and the machine element (17, 23). Adjusting elements (40a, 40b) as adjusting means of the machine element (17, 23) and further adjusting elements (41a, 41b) as adjusting means of the supports (19a, 19b) each have inclined surfaces (40a ', 40b', 41a ', 41b') as bearing surfaces on. The angles (a) of the inclined surfaces (40a ', 40b', 41a ', 41b') are formed in the same direction on both sides, and the machine element (17, 23) is in thermal expansion in its longitudinal direction (h) along the inclined surfaces ( 40a ', 40b', 41a ', 41b') with an actuator (47) as adjusting means displaceable (D, E; O, P), that the radial distance (a) remains the same.
