Abstract
Abstract A device for forming a supply bobbin from a thread advanced from a yarn supply includes a stationary winding drum having a winding space around the drum and defining an internal chamber and a slit connecting the winding space and the chamber. A rotatably mounted thread guide means for winding yarn on the winding space of the drum is included and a plurality of pins rotatably mounted within the chamber of the winding drum are provided for movement in an axial plane with respect to the winding drum through the slit one after the other. The pins successively exit and enter the chamber of the winding drum through the slit. Means are provided for so driving the pins continuously in a fixed transmission ratio with respect to the thread guide means that the pins exit from the chamber after a predetermined plurality of yarn windings have been formed on the winding space of the drum. The pins separate successive series of yarn windings by each momentarily forming a barrier for yarn windings.

Claim 1
Independent Claim
167 words
A device for forming a supply bobbin from a thread advanced from a yarn supply comprising, in combination, a stationary winding drum having a winding space around the drum and defining an internal chamber and a slit connecting the winding space and the chamber, rotatably mounted thread guide means for winding yarn on the winding space of the drum, a plurality of pins rotatably mounted within the chamber of the winding drum for movement in an axial plane with respect to the winding drum through the slit one after the other, the pins successively exiting and entering the chamber of the winding drum through the slit, and means for so driving the pins continuously in a fixed transmission ratio with respect to the thread guide means that the pins exit from the chamber after a predetermined plurality of yarn windings have been formed on the winding space of the drum, the pins separating successive series of yarn windings by each momentarily forming a barrier for yarn windings.
Claim 2
Independent Claim
167 words
A device for forming a supply bobbin from a thread advanced from a yarn supply comprising, in combination, a stationary winding drum having a winding space around the drum and defining an internal chamber and a slit connecting the winding space and the chamber, rotatably mounted thread guide means for winding yarn on the winding space of the drum, a plurality of pins rotatably mounted within the chamber of the winding drum for movement in an axial plane with respect to the winding drum through the slit one after the other, the pins successively exiting and entering the chamber of the winding drum through the slit, and means for so driving the pins continuously in a fixed transmission ratio with respect to the thread guide means that the pins exit from the chamber after a predetermined plurality of yarn windings have been formed on the winding space of the drum, the pins separating successive series of yarn windings by each momentarily forming a barrier for yarn windings.
Claim 3
Dependent Claim
47 words
A device according to claim 1 wherein the winding space around the drum includes a winding surface and a collar having an end face which gradually merges with the winding surface and in which the pins enter the winding space at the end face of the collar.
Claim 4
Dependent Claim
21 words
A device according to claim 2 wherein the thread guide means delivers the yarn to the end face of the collar.
Claim 5
Dependent Claim
28 words
A device according to claim 2 wherein the pins are mounted on a disk which is rotatable in an axial plane within the chamber of the winding drum.
Claim 6
Dependent Claim
28 words
A device according to claim 3 wherein the pins are mounted on a disk which is rotatable in an axial plane within the chamber of the winding drum.
Claim 7
Dependent Claim
43 words
A device according to claim 4 wherein the pins are so mounted movably on the disk and driven that they carry out a translational movement with the rotation of the disk and are always directed substantially radial with respect to the winding drum.
Claim 8
Dependent Claim
43 words
A device according to claim 5 wherein the pins are so mounted movably on the disk and driven that they carry out a translational movement with the rotation of the disk and are always directed substantially radial with respect to the winding drum.
