Abstract
Abstract Sliver is transported in large transport cans to a refilling device adjacent to a fine spinning machine having two parallel rows of spinning stations. The sliver is transferred from such large transport cans to supply cans which are smaller and are movable between the refilling station and individual spinning stations. At least four parallel supply can supporting tracks are provided, two of which are spinning head feeding tracks and two are refilling tracks. One refilling track receives empty supply cans transferred from the feeding tracks for circulation past the refilling station, and the other track receives the refilled supply cans for transfer to a spinning head feeding track. The refilling can tracks can be connected at both ends for unidirectional, or at one end for reversible, transfer of empty supply cans from one refilling track past a refilling device to the other track. The filled supply cans may be exchanged for emptied supply cans by connecting a spinning head feeding track to a refilling track and moving the supply cans along a continuous path, or by rails pushing filled supply cans transversely from a filling track onto an adjacent spinning head feeding track, thereby pushing empty supply cans onto another filling track.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
85 words
A method for supplying sliver to a plurality of spinning stations in a fine spinning machine, which comprises feeding sliver to such spinning stations from supply cans, transporting emptied supply cans to a refilling station, refilling such emptied supply cans at such refilling station with sliver from a transport can larger than such supply cans and containing sliver, the transport can having been received from a fiber-treating machine, and transporting such supply cans to such spinning stations for again feeding sliver from the supply cans.
Claim 2
Independent Claim
85 words
A method for supplying sliver to a plurality of spinning stations in a fine spinning machine, which comprises feeding sliver to such spinning stations from supply cans, transporting emptied supply cans to a refilling station, refilling such emptied supply cans at such refilling station with sliver from a transport can larger than such supply cans and containing sliver, the transport can having been received from a fiber-treating machine, and transporting such supply cans to such spinning stations for again feeding sliver from the supply cans.
Claim 3
Independent Claim
85 words
A method for supplying sliver to a plurality of spinning stations in a fine spinning machine, which comprises feeding sliver to such spinning stations from supply cans, transporting emptied supply cans to a refilling station, refilling such emptied supply cans at such refilling station with sliver from a transport can larger than such supply cans and containing sliver, the transport can having been received from a fiber-treating machine, and transporting such supply cans to such spinning stations for again feeding sliver from the supply cans.
Claim 4
Independent Claim
85 words
A method for supplying sliver to a plurality of spinning stations in a fine spinning machine, which comprises feeding sliver to such spinning stations from supply cans, transporting emptied supply cans to a refilling station, refilling such emptied supply cans at such refilling station with sliver from a transport can larger than such supply cans and containing sliver, the transport can having been received from a fiber-treating machine, and transporting such supply cans to such spinning stations for again feeding sliver from the supply cans.
Claim 5
Dependent Claim
79 words
The method defined in claim 1 for supplying sliver to a plurality of spinning stations in a fine spinning machine, the stations being arranged in a row at one side of the machine, including simultaneously removing from all of the spinning stations of such row supply cans from which sliver has been fed, and simultaneously placing in all the spinning stations of such row supply cans containing sliver to be fed to the respective spinning stations of such row.
Claim 6
Dependent Claim
89 words
The method defined in claim 2 for supplying sliver to a plurality of spinning stations in a fine spinning machine, the stations being arranged in rows at opposite sides, respectively, of the spinning machine, including simultaneously removing from the spinning stations of the rows at both sides of the spinning machine supply cans from which sliver has been removed, and simultaneously placing at all the spinning stations of both rows at opposite sides of the spinning machine supply cans containing sliver to be fed to the respective spinning stations.
Claim 7
Dependent Claim
155 words
The method defined in claim 2 for supplying sliver to a plurality of spinning stations in a fine spinning machine, the stations being arranged in two rows at opposite sides, respectively, of the machine, including simultaneously removing from all the spinning stations of a first row supply cans from which sliver has been Removed, simultaneously placing at all the stations of such row supply cans containing sliver from which sliver is to be fed to the spinning stations of such row while supply cans remain located undisturbed at the spinning stations of the other row, and, while the supply cans remain located undisturbed at the spinning stations of the first row, simultaneously removing from the spinning stations of the second row supply cans from which sliver has been removed and simultaneously placing at the supply stations of such second row supply cans containing sliver to be fed to the spinning stations of such second row.
Claim 8
Dependent Claim
59 words
The method defined in claim 2, in which the supply cans are removed from all of the spinning stations in a row and in a direction transversely of the length of such row, and, in placing the supply cans in the spinning stations, moving such cans in a row in a direction transversely of the length of such row.
Claim 9
Dependent Claim
52 words
The method defined in claim 2, in which the cans in being removed from the spinning stations are moved along one portion of an orbit away from the spinning stations, and the cans being placed in the spinning stations are moved along another portion of the same orbit toward such spinning stations.
Claim 10
Dependent Claim
81 words
The method defined in claim 3, in which refilling stations are located at opposite sides, respectively, of the fine spinning machine, cans removed from the spinning stations at the opposite sides of the fine spinning machine are moved toward their respective refilling stations along one portion of their respective orbits, and cans to be placed in the spinning stations at opposite sides of the spinning machine are moved toward such spinning stations along the same respective orbits from the refilling stations.
Claim 11
Dependent Claim
85 words
Mechanism for supplying sliver to a plurality of spinning stations in a fine spinning machine, comprising supply cans, means for feeding the stations from said supply cans, a refilling station, a transport can larger than said supply cans receivable in said refilling station and having been received from a fiber-treating machine, said refilling station including means for refilling said supply cans from said transport can, and means for moving said supply cans from said refilling station to the spinning stations of the fine spinning machine.
Claim 12
