Definitions

the present invention concerns a combing machine and respective comber groups for cotton strip particularly downwards drawing machines.
stumps (example of 20-30 centimeters) of fibers aligned tape (cotton strip) successively rolled up, these stumps after drawed being rejoined in new in cotton strips that successively is twined in wire form.
a gear transmission system as above exposed is bulky, complex and expensive and needs a container in closed box for the gears in bath of oil, with consequent frequent necessity of maintenance.
Scope of the present ' invention is to obviate to said drawbacks.
a tearing combing roll couple group rotating in both directions and between said combing roll and said tearing group, a nipper group with upper nipper jaw and lower nipper jaw mobile with the cotton and an upper guide comb for separation of the combed cotton from the continuous cotton strip, Characterized in that: - in at least one axis of said tearing couple of tearing group a step by step reversible electric motor is connected for their rotation - an electric corresponding impulses emitter of respective angular rotational values is associated to the rotation axis of said combing roll; - said electric impulses emitter is connected to a programmable computer to elaborate said impulses connected to said step by step reversible electric motor, in order that with opportune software , - it is possible to allow movement in programmed mode said tearing rolls both in clockwise and in counterclockwise direction in function of the corresponding impulses to determined rotation angles of said combing roll.
Figure 1 represents a frontal schematic view of an operator group according to the invention.
Figure 1 is a frontal schematic view of an operating group of the invention.
Figures 2 ,3 ,4 represent in transverse section the schematic view of three successive phases of the displacement of the comber group.
each comber group includes: - a combing roll (5) of the cotton fringe (p) involving a circular sector of combing tips (51 ); - a tearing combing roll couple group rotating in both directions (1 ) and between said combing roll (5) and said tearing group (1) , - a nipper group with upper nipper jaw (.2) and lower nipper jaw (4) mobile with the cotton (p) and an upper guide comb (3) for separation of the combed cotton (p1) by the continuous cotton strip (p) , characterized in that: - in at least one axis (121 ) of said tearing couple of tearing group (12) a step by step reversible electric motor (6) is connected for their rotation; - an electric corresponding impulses emitter of respective angular rotational values is associated to the rotation axis of said combing roll (52) ; - said electric impulses emitter is connected to one
- the drawer roll couples are two and each drawer roll couple involves a lower drawer motor toothed roll (112) and an upper idle smooth counterroll ( 1 1 1 ) .
- the- step by step driving motor(6) involves a reducer in which the motor axis act by central pinion (61 ) that commands in the same rotation in mesh two driven gears (62) coaxial and keyed with the respective axes of the drawer rolls (121 ).
FIG. 2 is illustrated the phase in which the cutting and guide group of the continuous cotton strip is portrayal and the combed stump (p1) is extracted to be conveyed to the throwing by means of rotation in counterclockwise sense of the drawer rolls 1 , while the combing roll (5) begins the combing of the cotton (p) advancing it by means of engagement with the own toothed sector (51 ); - in Figure 3 after combing that advanced the combed cotton being even in the same time advanced with the nipper guide group (2-3-4) toward the couples of the drawer rolls and after that these have taken the combed head of the cotton and advancement and when the combing roll (5) is disengaged from the cotton with the own combing sector (51 ), the respective rotation is inverted; - in Figure.4 it is shown the following phase at the moment of the clamping of the cotton with the comb 3, being the drawer rolls (1 ) again made rotate in advancing direction.
