MEANS FOR CLEANING THE ROLLERS OF SPINNING FRAMES Florimond Delepierre and Jules Charles Ghesquiers, Haubourdin, France, assig-nors to Societe fen Nom Collectif des Brevets Florimond Delepierre, Haub'ou'rdin, France Application' dctober 29, 1946,- Serial No. 706,422

, In. France-November 20, 1945 In continuous spinning frames, the roving'is drawn by passing it through-a, drawing head comprising a series of fluted rollers, usually three 2 Claims; (Cl.'1 9---139) in number, having journals rotatably mounted in bearings provided inroller stands, the said rollers co-operating with steel top pressure rollers having journals which'are rotatably guided in weighting saddles pivoted on the roller stands, the top pressure rollers co-operatingwith the last fluted roller to deliver the roving to the actual spinning devices being covered with leather.

v During the drawing operation, some of the fibres become detached from the roving, and drop down from the spinning frame, while other fibres leave the roving and remain attached to the drawing rollers or accumulate; behind the delivery rollers until they are pulled out by the thread in the form of a lump, resulting in a, defect in the yarn or breakage of the yarn while' thelatter is passing through the traveller of the ring.

Various devices are employed for cleaning the delivery rollers, the usual means employed for the purpose being in the form of wooden clearer rollers covered with velvet or rough cloth, which bear against the delivery rollers and rotate in opposite directions thereto. The clearer rollers of the top, leather-covered pressure rollers are applied thereto by their own weight, being provided with journals which are rotatable and slidable in guide forks fixed to the weighting saddles.

The coverings of the clearer rollers which pick up the fibres adhering to the top pressure rollers must themselves be regularly cleaned, and the present invention has for its object to provide an improved stripping mechanism for this purpose.

The accompanying drawings show diagrammatically, by way of example but not of limitation, one form of construction of the invention.

Figure l is a perspective view of the apparatus according to the invention, placed over the rollers of a continuous spinning frame.

Figure 2 is a profile view of the same apparatus.

Figure 3 is an end view of the larger base of one of the cones.

Figure 4 is a plan view of the apparatus.

Referring to the drawings, the drawing head illustrated comprises three fluted bottom rollers 21, 28, 29 which are rotatably mounted in bearings provided in roller stands 3! in the customary manner, the said rollers co-operating with top rollers I, 25, 30, respectively, the rollers 30 being covered with leather. The rollers I, 25, 30 are provided with journals which are rotatably guided in saddles 32 pivoted on the roller stands 3|,in the well-known manner. w

Clearer rollers 2 are provided for the rollers 30, the said clearer rollers being covered with velvet or cloth and serving for cleaning the rollers 30. The rollers 2 have journals 4i] which are rotatable and slidable in guide forksAI fixed to the saddles 32, so as to enable the rollers 2 to rest upon the rollers 30.

The drawings show a prismatic channel 3 forming a frame on which are fixed two cheekforming plates 4 and 5, provided with notchesli and 1, respectively, into which is placed the spindle 8 of a spool 9, upon which is arranged an endless cleaning card strip I0,the wires of which are on the outside. 7

Several pairs of brackets II and I2,..the flattened heads of which each comprise a hole for the passage of the spindle I3 of a truncated cone I l, are fixed to the frame. These brackets II and I 2 can slide in a mortise reserved in guard pieces I5 fixed to the channel member 3, and a set screw I 6 (Figure 2) locks the said brackets in position.

These brackets are so fixed that the axes of rotation of the cones are substantially parallel.

If, as indicated in Fig. 1, the apparatus is so placed that the channel member covers the rollers I and so that the cones rest obliquely on the cloth-covered rollers 2, the rotation of the latter turns the cones I4 about their respective axes and causes them to advance in the direction opposite to the 'apioes of the cones, thus carrying along with them the frame 3, which slides above the saddles 32. The cleaning card strip I0, which is always in contact with the cloth-covered rollers, brushes the latter and removes the textile fibres adhering thereto.

In spinning machines, the cloth-covered rollers are not all of strictly the same diameter, and are not all in the same alignment. In order that the cones may not be stopped in their advance, the larger base of each cone comprises an eccentrically disposed end portion I I of reduced diameter, as represented on a larger scale in Figure 3. This eccentric portion I1 is tangential at I8 to the base of the cone. In order that the cones may remain in contact with the rollers, their axes of rotation are free to oscillate, and for this purpose the holes in the flattened heads of the brackets II and I2 are elongated, as represented at I9 in Figure 3.

When the rollers 2 are rotated by frictional contact with the rollers 30, the cones I4 will be turned by frictional contact with the rollers 2 and will advance slowly in the direction opposite to the apices of the cones. The speed of advance of the cones increases with the angle formed by the axes thereof with the longitudinal axes of the rollers 2 V g I On any cone, during "its advance, encountering a roller 2 of larger diameter, the eccentric portion I! of the cone will climb smoothly upon the end of the said roller.

Thus the apparatus advances slowly along the spinning frame and removes the fibres that adhere to the velvet-covered or clothcovered rollers, these fibres remaining entangled withthe wires of the strip of cleaning card. When this cleaning card is full of fibres, it can easilybe replaced by a clean strip.

As represented in Figures1 and 2, the cheeks 4 and 5 may advantageously be extended, and may comprise notches 23 and 23! enabling the apparatus to be hung on to any cross-member of the spinning frame when not being used.

As indicated in Figure 2 the apparatus may be supplemented by a brush 24, which sweeps off the fibres and dust deposited on a roller 25.

We claim:

1. A travelling cleaning device for continuous spinning'frames and like textile machines having a drawing head embodying a plurality of parallel rows of r'ollers,comprising in combination, a frame freely slidable along one of said rows of rollers, a clearing element carried by said frame and in contact with the rollers of an adjacent parallel row of rollers, brackets on said frame and traversing means for the frame, comprising a plurality of cones rotatably mounted in said brackets and in contact with the rollers of said adjacent row with their axes at an angle to a plane containing the axes, of said rollers, so as to rotate with'and travel along the rollers of said adjacent row in the direction opposite to the 4 apices of the cones, each cone having an eccentric end portion of reduced diameter tangential to the base of the cone.

2. A travelling cleaning device for continuous spinning frames and like textiles machines having a drawing head embodying a plurality of parallel rows of rollers, comprising in combination, a frame freely slidable along one of said rows of rollers, a pair of upright cheeks secured to the frame, a spool freely rotatable between said cheeks, a clearing element comprising an endless strip of card clothing extending around said spool with its wires in contact with the rollers of an adjacent parallel row of rollers, brackets on said frame and traversing means for the frame, comprising a plurality of cones rotatably mounted in said brackets and in contact with the rollers of said adjacent row with their axes at an angle to aplane containing the axes of said rollers, so as to rotate with and travel along the rollers of said adjacent row.
