Abstract

Device at a card for textile fibre, cotton, chemical fibres made of cover bars provided with fittings and the tops of the drum mounting a distance is existent. The cover bars slide with their both ends covex curve sliding guides, each of which are built being formed by a flexible element, which is arranged to a convex surface of the accompanying flexible bend wherein the sliding guide is displaceable in radial direction (x1) in such a manner, that the distance (a) between the tops of the cover mountings and the tops of the drum fitting remains uniform at all the points through the circumference.

Full Text	With the cover mounting and the distance between the mountings, in the same manner. Such a new adjustment of the flexible bend is expensive. Besides that, the geometry of the flexible bend is dependent on the number of the adjusting screws. For this purpose lateral card elements, for example, drive, suction and also the cover rod are to be mounted time and again in the stand-still condition. This is fraught with substantial erection expenses. Besides, that, through the standstill position and running production operation of the card is interrupted. The Invention therefore, makes the problem as the basis, to arrange for a device of the nature described in the beginning, which avoids the mentioned disadvantages, which renders possible especially a change of the intensity of carding in a simple manner, preferably during the running of the operation. The solution of this problem takes place through the characteristic features as described herein under. It is possible through the measures, in accordance with the Invention, to change as reaction on alterations of technological magnitude, for example, Nissen-digit and/or fibre damage, which change the intensity of the carding in a simple manner. A further special advantage exists therein, that after successful displacement of the sliding guide the uniform distance between the cover mountings and the drum mounting at all the stages through the circumference remains retained, whereby a substantial improvement of the generated fibre band is achieved. The position of the convex outer surface of the sliding guide is radially shifted. The flexibility (elasticity) of the sliding guide ensures, that the bend form of the outer surface of the sliding guide is matchable, so that thereby the uniformity of the distance between the cover and the drum fitting is ensured at all positions throughout the circumference. A further advantage existing therein, that the shifting can take place continuously, for example, in operation also. That can take place automatically or on "button press" without delay, whereby each time- consuming erection expenses and each production interruption can be avoided. It is specially further advantageous, that the convex outer surface of the sliding guide-on which the convering head lies on each case - is shifted on both the sides of the machine concentrically for the drum circumference (drum shell) in radial direction. In this manner it becomes possible to shift endlessly many supporting points for the cover-heads continuously. It is provided functionally that the distance between the convex outer surface of the sliding guide and of the concave inner surface of the sliding guide in the circumferential direction decreases rather increases and the distance between the convex bearing surface of the flexible bend and between the axle of the drum accordingly increases rather decreases, so that the total of both the distances at all positions through the circumference is constant. According to a further advantageous development, in case of which the distance between the curved (arched) convex outer surface of the sliding guide and the concave inner surface of the sliding guide is constant, is realized, that between the sliding guide and the bearing surface of the flexible bend an intermediate layer is existent and the distance between the concave out surface of the intermediate layer of the convex inner surface of the intermediate layer in the circumferential direction decreases rather increases and the distance between the convex bearing surface of the flexible bend and of the axle of the drum accordingly increases or decreases, so that the total of both the distances at all the positions through the circumference is constant.

A reversible motor is indicated with 44. The sliding guide 20 is attached at its one end through a tension spring 34 to a fixed bearing according to the Fig. No. 13. With the help of the driven cover guide roller 13a a tension is exerted on the sliding guide 20 in the direction of R. Between the sliding guide 20 and the flexible bend 17 an intermediate layer 20 is existent, which is shiftable in the direction of the arrow-head D. E (please compare Fig. No. 5).

With the cover mounting and the distance between the mountings, in the
same manner. Such a new adjustment of the flexible bend is expensive.
Besides that, the geometry of the flexible bend is dependent on the number
of the adjusting screws. For this purpose lateral card elements, for example,
drive, suction and also the cover rod are to be mounted time and again in
the stand-still condition. This is fraught with substantial erection expenses.
Besides, that, through the standstill position and running production
operation of the card is interrupted. The Invention therefore, makes the
problem as the basis, to arrange for a device of the nature described in the
beginning, which avoids the mentioned disadvantages, which renders
possible especially a change of the intensity of carding in a simple manner,
preferably during the running of the operation.
The solution of this problem takes place through the characteristic features
as described herein under.
It is possible through the measures, in accordance with the Invention, to
change as reaction on alterations of technological magnitude, for example,
Nissen-digit and/or fibre damage, which change the intensity of the carding
in a simple manner. A further special advantage exists therein, that after
successful displacement of the sliding guide the uniform distance between
the cover mountings and the drum mounting at all the stages through the
circumference remains retained, whereby a substantial improvement of the
generated fibre band is achieved. The position of the convex outer surface
of the sliding guide is radially shifted. The flexibility (elasticity) of the
sliding guide ensures, that the bend form of the outer surface of the sliding
guide is matchable, so that thereby the uniformity of the distance between
the cover and the drum fitting is ensured at all positions throughout the
circumference. A further advantage existing therein, that the shifting can
take place continuously, for example, in operation also. That can take place
automatically or on "button press" without delay, whereby each time-
consuming erection expenses and each production interruption can be
avoided. It is specially further advantageous, that the convex outer surface
of the sliding guide-on which the convering head lies on each case - is
shifted on both the sides of the machine concentrically for the drum
circumference (drum shell) in radial direction. In this manner it becomes
possible to shift endlessly many supporting points for the cover-heads
continuously.

sliding guide and the concave inner surface of the sliding guide is constant,
is realized, that between the sliding guide and the bearing surface of the
flexible bend an intermediate layer is existent and the distance between the
concave out surface of the intermediate layer of the convex inner surface of

convex outer surface 20a is displaced in the direction of the arrow-head U
upwards, whereby at the same time the cover bar is displaced with the
cover tip 14a, 14b (only 14b is represented) in the direction of the arrow-
head T upwards, so that the distance (b) between the cover to 14a, 14b and
