Abstract
Abstract Two rows of cans, the number of which corresponds to half of the number of spinning units in a spinning frame, are arranged along each side of the spinning frame, with the inside cans half full of slivers and the outside cans full of slivers before starting the operation. Slightly before the slivers in the inside cans are used up, their ends are pieced with the slivers in full cans previously supplied in their standing-by positions backwardly of the outside row of cans. The empty cans in the inside row are moved inwardly onto a conveyer between the inside can rows and then the cans in the outside row, which are now half full of the slivers, are moved in the inside row and the cans in the standing-by positions are also moved in the outside row. The empty cans on the conveyer can be removed out of the spinning machine by driving the conveyer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A method of effecting replacement of cans in a spinning frame of the type in which slivers contained in the cans are directly supplied to lined up spinning units of the spinning frame, which comprises, disposing the cans in inside and outside rows along the length of the spinning frame, the cans in the inside row containing about half as much slivers as the cans in the outside row, disposing a row of cans full of slivers backwardly of the outside cans therealong, the number of the full cans corresponding to that of the cans in one of the inside and outside rows, piecing the slivers in the full cans with the slivers in the cans in the inside row as the inside cans are ready to empty, removing the inside cans from the inside row inwardly onto a movable carrying out path arranged inside the inside row of the cans to extend along and out of the spinning frame, moving the outside cans inwardly into the inside row, and moving the full cans inwardly into the outside row.
Claim 2
Independent Claim
179 words
A method of effecting replacement of cans in a spinning frame of the type in which slivers contained in the cans are directly supplied to lined up spinning units of the spinning frame, which comprises, disposing the cans in inside and outside rows along the length of the spinning frame, the cans in the inside row containing about half as much slivers as the cans in the outside row, disposing a row of cans full of slivers backwardly of the outside cans therealong, the number of the full cans corresponding to that of the cans in one of the inside and outside rows, piecing the slivers in the full cans with the slivers in the cans in the inside row as the inside cans are ready to empty, removing the inside cans from the inside row inwardly onto a movable carrying out path arranged inside the inside row of the cans to extend along and out of the spinning frame, moving the outside cans inwardly into the inside row, and moving the full cans inwardly into the outside row.
Claim 3
Dependent Claim
25 words
A method as claimed in claim 1 in which said full cans are disposed by actuating a movable supply path upon indication from an auto-counter.
Claim 4
Dependent Claim
43 words
A method as claimed in claim 2, which further comprises, transporting the empty cans on the carrying out path to a drawing frame to be filled with slivers and transporting the cans full of slivers from the drawing frame to the spinning frame.
Claim 5
Independent Claim
263 words
An apparatus for replacement of cans in a spinning frame of the type in which slivers contained in the cans are directly supplied to lined up spinning units of the spinning frame, said apparatus comprising at least one first space for allowing the cans to be disposed in paired inside and outside rows along the length of the spinning frame, the cans in the inside row containing about half as much slivers as the cans in the outside row, a second space for allowing a row of cans full of slivers to be disposed backwardly of the outside cans therealong, the number of the full cans corresponding to that of the cans in one of the inside and outside rows, a third space provided in the lower part of the spinning frame for allowing the cans in the inside row to be received therein, said third space including a movable carrying out means arranged inside the inside row of the cans to extend along and out of the spinning frame, whereby the replacement of the cans is carried out by moving the inside cans in said firsT space onto said movable carrying out path of said third space after piecing the slivers in the full cans of said second space with the slivers in the cans in the inside row of said first space as the inside cans are ready to empty, moving the outside cans inwardly into the inside row within said first space, and moving the full cans of said second space inwardly into the outside row of said first space.
Claim 6
Independent Claim
263 words
An apparatus for replacement of cans in a spinning frame of the type in which slivers contained in the cans are directly supplied to lined up spinning units of the spinning frame, said apparatus comprising at least one first space for allowing the cans to be disposed in paired inside and outside rows along the length of the spinning frame, the cans in the inside row containing about half as much slivers as the cans in the outside row, a second space for allowing a row of cans full of slivers to be disposed backwardly of the outside cans therealong, the number of the full cans corresponding to that of the cans in one of the inside and outside rows, a third space provided in the lower part of the spinning frame for allowing the cans in the inside row to be received therein, said third space including a movable carrying out means arranged inside the inside row of the cans to extend along and out of the spinning frame, whereby the replacement of the cans is carried out by moving the inside cans in said firsT space onto said movable carrying out path of said third space after piecing the slivers in the full cans of said second space with the slivers in the cans in the inside row of said first space as the inside cans are ready to empty, moving the outside cans inwardly into the inside row within said first space, and moving the full cans of said second space inwardly into the outside row of said first space.
Claim 7
Dependent Claim
46 words
An apparatus as claimed in claim 4, wherein two first spaces are provided on the opposite sides of the spinning frame to be in communication with said third space and said movable carrying out means consists of a single conveyer centrally disposed in said third space.
Claim 8
Dependent Claim
33 words
An apparatus as claimed in claim 4, wherein part of said first space is provided in the lower part of the spinning frame to reduce a floor area required for said first space.
Claim 9
Dependent Claim
29 words
An apparatus as claimed in claim 4, wherein said movable carrying out path includes conveyer means connected with a group of drawing frames to convey the empty cans thereto.
Claim 10
Dependent Claim
71 words
An apparatus as claimed in claim 7, wherein said second space includes a movable full can supply path consisting of a conveyer which is associated with said conveying means connected with the drawing frame group to convey the full cans from the drawing frame group to the spinning frame group, whereby the cans are circulated through said first, second and third spaces, the drawing frame group and the spinning frame group.
