is a specification.

This invention relates to cross winding machines in which a spool is rotated by means of a friction drum provided with a groove for driving the thread guide.

The main object of my invention is to provide a machine which has a higher efii: ciency than those hitherto known and in which there is less wear of the working I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figures 1 and 2 which are respectively an elevation and a left hanc side view of the cross winding machine.

Figure 3 is an enlarged section on line 3-3 of Figure 1.

Figures 41: to 6 are respectively an enlarged side view, a plan and a vertical section of the thread guide. 1

Figure 7 is an enlarged detached detail view of Figure2.

Figure 8 is a vertical section on line 88 of Figure 7. a j

Figure 9 is a horizontal section on line 9-9 of Figure 2, drawn to a reduced scale.

Figures 10 to 12 are respectively an enlarged side view, a plan and a vertical section of a double thread guide;

The rotated drum 1 has a driving groove 2 for the thread guide 3, located at an incline to the drum axis and the rear side of the thread guide 3, is so curved that it fits the rounded contour of the drum.

A cylindrical projection 4 forced out of the rear wall of the hollow thread guide 3 engages the driving groove 2 of the drum. The front wall of the thread guide is connected by a rib with the rear wall and has a vertical open groove 5, for the guidance of the thread 6. The substantially circular thread guide 3 terminates at the bottom in a fiat portion and thus a sharp edge 7 substantially perpendicular to the thread is produced where the thread leaves the groove 5 whereby any tendency of the thread to ride up the edges of the lower end of the groove 5 and leave the groove laterally during the to and fro movement of the thread guide is overcome. The front wall of the latter has further an open groove 8 for the reception of a guide rod 9 which retains the thread guide in position on thedrum duringits to and fro movement." The front wall 3' is so curved that the thread dur ing the first to and fro movement of the guide will enter the groove 5 automatically and that on pushing the guide into its working position from below, the resilient guide rod 9 will be forced outwardly by the guide and then spring into the groove 8 whereby fixing of the guide on the drum is considerably facilitated. In order torernove the thread guide from the drum, all that is necessary is to slightly bend therod 9 o'utwardly and to slide the guide upwards or downwards. I Owing to the weight of the metal thread guide being only about two grammes,it can operate without shocks and noise at a very high speed, whereby the efiiciency or output of the machine is considerably increased.

The guide rod 9 is carried by two adjustably fixed arms 11, Figures 2 and 7 to 9, and by angular adjustment of the arms 1' 11 on the shaft 10, the distance of the rod 9 and therefore of the'thread guide from the place of contact of the spool 12 or material 12 (Figure 3) wound on the'spool'with the drum 1 can be varied.

In order to permit of regulating the distance between the guide rod 9 and the drum and thereby the degree of contact of the thread guide with the drum, each end of the rod is mounted in a radial slot 13 in a cylindrical part 14 mounted in the respective arm 11.

The slot 13 is engaged by a short tongue 15 provided on a plate 17 which rests on the part 14 and is formed with a slot 16 (Figures 7 and 8). By adjustment of this plate on arm 11, the part 1 1 is turned in the arm 11 and the rod 9 is thereby caused to approach or recede from the drum 1. After the rod 9 has been set at the correct distance from the drum it is locked in position by tightening screws 18 which engage the slot 16 of the plate 17 and by tightening a nut 19 which screws on the part 14. The nut 19 is locked by engagement in the groove 21 of the nut, of the forked channel like and resilient ends 20 on the plate 17.

Figures 13 and 14 show a thread guide 3 which is separated by a partition 30 into two grooves 5 and 5' for two threads where the drum; at least one open groove in the frontside of the guide to guide the thread; a guiding and holding member for the guide; and an open groove in the front side of the guide for the reception of the said guiding and holding member.

2. In a cross winding machine adapted to rotate aspool by means of a friction drum provided with a driving groove for a thread guide, a thread guide; and a resilient rod adapted to serve as a guide for the thread guide and removably hold it in sliding contact with the periphery of the drum.

3. In a cross winding machine adapted to rotate a spool by means of a friction drum provided with a driving groove for the thread guide, a thread guide; a groove in the front of the thread guide; a resilient holder for the guide; and a curved front surface onthe thread guide adapted by the sliding movement of the guide to automatically cause the thread to enter the said groove and to facilitate fixing and removal of thread guide on and from the drum by a bending of the resilient holder.

4:. In a cross winding machine adapted to rotate a spool by means of a friction drum provided with a driving groove for a thread guide, a thread guide: a thread groove in the thread guide; and a flat side on the thread guide parallel with the drum axis and facing the spool, whereby the thread is and conforming with the curvature of the drum.

6. In a cross winding machine having a spool rotated by friction from a drum provided withla driving groove for athread guide, a thread guide; a stamped sheet metal piece formingone part of the thread guide;

guide grooves in said piece; a stamped sheet metal piece forming the other part of the thread guide and secured to the first'named piece by a folding; anda projection on the second named piece adapted to engage the driving groove of the drum.

7. In a cross winding machine having a spool rotated by friction from a drum provided with a driving groove for a thread guide, a thread guide; two thread guiding grooves therein; and a partition separating the two grooves.

8. In a cross winding machine having a spool rotated by friction from a drum provided with a driving groove for the thread guide; a thread guide; a guiding andholding member for said thread guide; and adjusting means whereby said member can b adjusted relative to the drum.

9. In a cross winding machine having a spool rotated by friction from a drum provided with a driving groove for a thread guide, a thread guide; a guiding and hold ing member for said thread guide; and adjusting means whereby said member can be adjusted, about the drum axis.
