Abstract
Abstract Cleaning apparatus for textile machines disposed in a row, which cleaning apparatus can be moved back and forth among the textile machines. The cleaning apparatus has blow hoses provided with nozzles to blow off loose fuzz from the textile machines, and at least one suction hose for sucking up the blown off fuzz. For each textile machine at least one stationary blower is disposed at the machine side opposite from the suction hose and has at least one blast nozzle for blowing air covering the floor below the textile machines. The cleaning apparatus has a vertically extending, relatively rigid air blast duct which docks at the blower when the cleaning apparatus is aligned with the blower.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
113 words
A cleaning device for textile machines disposed in a row, comprising a cleaning apparatus for movement back and forth above said machines including blow hoses provided with nozzles for blowing off loose fuzz and at least one suction hose for sucking up the blown off fuzz, at least one stationary blowing means disposed at a side of each machine opposite the suction hose, the blowing means having at least one blast nozzle for blowing air so as to cover the floor below the textile machine, the cleaning apparatus having a vertically extending, substantially rigid air blast duct for docking at the blowing means when the cleaning apparatus is aligned with the blowing means.
Claim 2
Dependent Claim
113 words
A cleaning device for textile machines disposed in a row, comprising a cleaning apparatus for movement back and forth above said machines including blow hoses provided with nozzles for blowing off loose fuzz and at least one suction hose for sucking up the blown off fuzz, at least one stationary blowing means disposed at a side of each machine opposite the suction hose, the blowing means having at least one blast nozzle for blowing air so as to cover the floor below the textile machine, the cleaning apparatus having a vertically extending, substantially rigid air blast duct for docking at the blowing means when the cleaning apparatus is aligned with the blowing means.
Claim 3
Dependent Claim
24 words
A cleaning device according to claim 1, including means for stopping the cleaning apparatus while the cleaning apparatus is docked at the blowing means.
Claim 4
Dependent Claim
28 words
A cleaning device according to claim 1 including means for docking the air blast duct at the blowing means before the cleaning apparatus travels over the textile machine.
Claim 5
Dependent Claim
26 words
A cleaning device according to one of claims 1, 2 or 3, including means for throttling the air supply to the blow hoses during said docking.
Claim 6
Dependent Claim
56 words
A cleaning device according to claim 4, further including elastic sealing lamellae surrounding the end of the duct disposed at the docking end of the air blast duct, a shield surrounding the opening of the blowing means, said sealing lamellae disposed so as to abut said shield surrounding the opening of the blowing means during docking.
Claim 7
Dependent Claim
54 words
A cleaning device according to claim 4, in which the blowing means has a blast nozzle which can be turned about a vertical axis of rotation; means for causing said blast nozzle to rotate while docking about 90 degrees between positions which are transverse and parallel to the longitudinal axis of the textile machine.
Claim 8
Dependent Claim
26 words
A cleaning device according to claim 6, in which the means for causing the blast nozzle to rotate is a docked and rotating air blast duct.
Claim 9
Dependent Claim
31 words
A cleaning device according to claim 6, in which the means for causing the blast nozzle to rotate is the cleaning apparatus while passing the blast nozzle and air blast duct.
Claim 10
Dependent Claim
38 words
A cleaning device according to claim 6, in which the lower end of the air blast duct is angled so as to engage with an angled portion of the blowing means extending parallel to the air blast duct.
Claim 11
Dependent Claim
49 words
A cleaning device according to one of claims 1, 2 or 3, in which the blowing means has a duct which extends horizontally along the textile machines and has several blast nozzles, said duct being connected to at least one connecting tube at which the air blast duct docks.
Claim 12
Dependent Claim
20 words
A cleaning device according to claim 10, in which the duct has a connecting tube at each of its ends.
Claim 13
Dependent Claim
29 words
A cleaning device according to claim 11, in which a valve, opening in the direction of the duct, is disposed between the duct and each of the connecting tubes.
Claim 14
Dependent Claim
31 words
A cleaning device according to claim 11, including means for stopping the air supply to the air blast duct when the second connecting tube, seen in direction of travel, is passed.
Claim 15
Dependent Claim
56 words
A cleaning device according to claim 10, further including elastic sealing lamellae surrounding the end of the duct disposed at the docking end of the air blast duct, a shield surrounding the opening of the blowing means, said sealing lamellae disposed so as to abut said shield surrounding the opening of the blowing means during docking.
Claim 16
Dependent Claim
61 words
A cleaning device according to one of claims 1, 2 or 3, further including elastic sealing lamellae surrounding the end of the duct disposed at the docking end of the air blast duct, a shield surrounding the opening of the blowing means, said sealing lamellae disposed so as to abut said shield surrounding the opening of the blowing means during docking.
Claim 17
Dependent Claim
59 words
A cleaning device according to one of claims 1, 2 or 3, in which the blowing means has a blast nozzle which can be turned about a vertical axis of rotation; means for causing said blast nozzle to rotate while docking about 90 degrees between positions which are transverse and parallel to the longitudinal axis of the textile machine.
Claim 18
Dependent Claim
26 words
A cleaning device according to claim 16, in which the means for causing the blast nozzle to rotate is a docked and rotating air blast duct.
Claim 19
Dependent Claim
38 words
A cleaning device according to claim 17, in which the lower end of the air blast duct is angled so as to engage with an angled portion of the blowing means extending parallel to the air blast duct.
Claim 20
Dependent Claim
31 words
A cleaning device according to claim 16, in which the means for causing the blast nozzle to rotate is the cleaning apparatus while passing the blast nozzle and air blast duct.
Claim 21
Dependent Claim
38 words
A cleaning device according to claim 19, in which the lower end of the air blast duct is angled so as to engage with an angled portion of the blowing means extending parallel to the air blast duct.
Claim 22
Dependent Claim
37 words
A cleaning device according to claim 16, in which the lower end of the air blast duct is angled so as to engage with an angled portion of the blower extending parallel to the air blast duct.
Claim 23
Dependent Claim
34 words
A cleaning device according to claim 21, including means in the cleaning apparatus for stopping the air supply to the air blast duct while a second blowing means, seen in direction of travel, docks.
