Abstract
A spinning frame having a frame mount, a plurality of spindles and, suction elements for each spindle, a ventilating fan arranged in the frame mount and connected to the suction elements, and a filter on the pressure side of the ventilating fan, the filter forming at least part of the rear wall of the frame mount, and including pneumatic cleaning means for the filter, said cleaning means including a suction arm which is movable along the filter and is connected to a suction device.
Claims6
A spinning frame containing spindles and comprising:
- a frame mount;
- a ventilating fan arranged in cooperating relationship with respect to said frame mount and the spindles of the spinning frame;
- said ventilating fan having a suction side and a pressure side;
- a filter located at the pressure side of said ventilating fan;
- said filter forming at least part of a rear wall of said frame mount;
- pneumatic cleaning means provided for said filter;
- said pneumatic cleaning means comprising:
- a suction arm which is movable along said filter;
- and
- a suction device connected to said suction arm;
- and
- said movable suction arm overlying a portion of the filter which is being cleaned and diminishing the action of the ventilator fan upon the filter, so that waste deposited upon said filter is effectively entrained away from said filter by the action of the cleaning means.
A spinning frame containing spindles and comprising:
- a frame mount;
- a ventilating fan arranged in cooperating relationship with respect to said frame mount and the spindles of the spinning frame;
- said ventilation fan having a suction side and a pressure side;
- a filter located at the pressure side of said ventilating fan;
- said filter forming at least part of a rear wall of said frame mount;
- pneumatic cleaning means comprising:
- a suction arm which is movable along said filter;
- and
- a suction device connected to said suction arm;
- an air duct operatively connected with said suction device;
- said frame mount having a rear wall;
- said air duct extending in longitudinal direction adjacent said rear wall of said frame mount;
- said air duct having a longitudinally movable part;
- said suction arm being operatively connected to said longitudinally movable part;
- and
- said longitudinally moving part constituting a portion of a wall of said air duct.
A spinning frame containing spindles and comprising:
- a frame mount;
- a ventilating fan arranged in cooperating relationship with respect to said frame and the spindles of the spinning frame;
- said ventilating fan having a suction side and a pressure side;
- a filter located at the pressure side on said ventilating fan;
- said filter forming at least part of a rear wall of said frame mount;
- pneumatic cleaning means provided for said filter;
