Abstract

Abstract An electro-mechanical pull skein winder which automatically and sequentially operates 1) the winding mechanism that winds you on a spindle, 2) the doffing means that pushes the wound skein off the spindle, 3) the clamping means that grip the tail end of the skein of yarn just doffed, 4) the cutting means that severs the wound skein from the continuous length of yarn and 5) the ejecting means that deposit the skein at a particular point, and then automatically starts the cycle over again.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 231 words
An automatic pull skein winding machine comprising a. spindle means supported at only one end upon which a skein of yarn is to be wound, said spindle meAns comprising a spindle having an axial bore, a sleeve extending at least partially into said bore and being fixedly mounted thereon such that rotation of said sleeve causes said spindle to rotate at the same time, b. means for rotating said spindle means to wind a skein of yarn directly on the outer surface of said spindle, c. means to lay the yarn directly on the outer surface of said spindle with said means being mechanically connected to traversing means that lay the yarn directly on the spindle along its length as the spindle rotates, d. means for doffing the skein off the open end of said spindle while the spindle remains fixedly mounted on said sleeve, said means for doffing the wound skein comprising a doffing ring of a diameter slightly larger than the diameter of said spindle, e. means at the unsupported end of the spindle for clamping the yarn tail of the just doffed skein in a fixed position relative to said spindle, f. shaft means in said sleeve for actuating said clamping means, g. means for severing the yarn between the doffed skein of yarn and the clamping means which holds the yarn tail of the just doffed skein.
Claim 2
Dependent Claim 231 words
An automatic pull skein winding machine comprising a. spindle means supported at only one end upon which a skein of yarn is to be wound, said spindle meAns comprising a spindle having an axial bore, a sleeve extending at least partially into said bore and being fixedly mounted thereon such that rotation of said sleeve causes said spindle to rotate at the same time, b. means for rotating said spindle means to wind a skein of yarn directly on the outer surface of said spindle, c. means to lay the yarn directly on the outer surface of said spindle with said means being mechanically connected to traversing means that lay the yarn directly on the spindle along its length as the spindle rotates, d. means for doffing the skein off the open end of said spindle while the spindle remains fixedly mounted on said sleeve, said means for doffing the wound skein comprising a doffing ring of a diameter slightly larger than the diameter of said spindle, e. means at the unsupported end of the spindle for clamping the yarn tail of the just doffed skein in a fixed position relative to said spindle, f. shaft means in said sleeve for actuating said clamping means, g. means for severing the yarn between the doffed skein of yarn and the clamping means which holds the yarn tail of the just doffed skein.
Claim 3
Dependent Claim 26 words
An automatic pull skein winding machine as recited in claim 1 further comprising a doffing tray into which the doffed skein is ejected from said spindle.
Claim 4
Dependent Claim 51 words
An automatic pull skein winder as recited in claim 2 wherein said means for severing the yarn comprises a shaft upon which said doffing tray is mounted and means for rotating said shaft through a predetermined arc whereby the yarn tail of just doffed skein is inserted in said clamping means.
Claim 5
Dependent Claim 33 words
An automatic pull skein winder as recited in claim 2 wherein said means for severing the yarn comprises scissor knife cutting means mounted on a shaft to which said doffing tray is mounted.
