Abstract
In the case of an arrangement for the cleaning of the circumferential surface of a delivery roller pair of a drafting unit of a spinning machine, devices are provided for the reinforcing of the cleaning effect while the drafting unit starts up again after a stoppage. Heating devices are also disclosed for heating the pressure rollers before a piecing operation is started.
Claims21
An arrangement for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure roller during normal spinning operations,
- increased cleaning apparatus for increasing cleaning effects on the circumferential surface of the pressure roller to a higher level than during normal spinning operations,
- and selectively operable actuating apparatus for selectively actuating the increased cleaning apparatus during a restarting of the drafting unit after a stoppage for deactuating the increased cleaning apparatus during normal spinning operations,
- wherein the cleaning suction device includes a first suction nozzle assigned to the pressure roller of the pair of delivery rollers, and wherein the increased cleaning apparatus includes a second suction nozzle which is operable with a stronger vacuum than the first nozzle.
An arrangement for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure roller during normal spinning operations,
- increased cleaning apparatus for increasing cleaning effects on the circumferential surface of the pressure roller to a higher level than during normal spinning operations,
- and selectively operable actuating apparatus for selectively actuating the increased cleaning apparatus during a restarting of the drafting unit after a stoppage for deactuating the increased cleaning apparatus during normal spinning operations,
- wherein the increased cleaning apparatus includes selectively operable hating apparatus for the heating of the pressure roller.
An arrangement for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure roller during normal spinning operations,
- increased cleaning apparatus for increasing cleaning effects on the circumferential surface of the pressure roller to a higher level than during normal spinning operations,
- selectively operable actuating apparatus for selectively actuating the increased cleaning apparatus during a restarting of the drafting unit after a stoppage for deactuating the increased cleaning apparatus during normal spinning operations,
- and a mobile servicing carriage for servicing the drafting unit,
- wherein the increased cleaning apparatus includes at least one component carried on the servicing carriage, and wherein the increased cleaning apparatus includes a suction nozzle carried by the servicing carriage.
An arrangement for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure roller during normal spinning operations,
- increased cleaning apparatus for increasing cleaning effects on the circumferential surface of the pressure roller to a higher level than during normal spinning operations,
- selectively operable actuating apparatus for selectively actuating the increased cleaning apparatus during a restarting of the drafting unit after a stoppage for deactuating the increased cleaning apparatus during normal spinning operations,
- and a mobile servicing carriage for servicing the drafting unit,
- wherein the increased cleaning apparatus includes at least one component carried on the servicing carriage, and wherein the increased cleaning apparatus includes a heating device for heating a pressure roller.
An method for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- operating a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure rollers during normal spinning operations, and
- selectively operating an increased cleaning apparatus to increase the cleaning effects on the circumferential surface of the pressure roller as compared to normal spinning operations, during a restarting of the drafting unit after a stoppage, wherein the increased cleaning apparatus includes a heating device for heating a pressure roller, and wherein the selectively operating an increased cleaning apparatus includes actuation of said heating unit during a restarting of the drafting unit after a stoppage.
A method for cleaning the circumferential surface of a pressure roller of a pair of delivery rollers of a drafting unit of a spinning machine, comprising:
- operating a cleaning suction device assigned to the circumferential surface of the pressure roller for cleaning the pressure rollers during normal spinning operations, and
- selectively operating an increased cleaning apparatus to increase the cleaning effects on the circumferential surface of the pressure roller as compared to normal spinning operations, during a restarting of the drafting unit after a stoppage, wherein the cleaning suction device includes a first suction nozzle assigned to the pressure roller of the pair of delivery rollers, and wherein the selectively operating an increased cleaning apparatus includes actuation of a second suction nozzle which is operable with a stronger vacuum than the first nozzle.
