Abstract
A fiber processing machine has rotary components, a shroud surrounding the components at least laterally and from above, a suction apparatus including at least one suction head situated in the space surrounded by the shroud for drawing away, by means of an air stream, fiber waste released during operation of the machine. There is provided at least one blower head which is located between the rotary components and the shroud for introducing pressurized air into the space surrounded by the shroud.
Claims12
A carding machine having length and width dimensions, comprising in combination:
- (a) a plurality of rotary roll and drum components arranged in said length dimension and each having a rotary axis oriented parallel to said width dimension;
- (b) a shroud extending along said length dimension and enclosing said components on top and along opposite sides;
- (c) a blower head situated in a radial space bounded, at opposite sides of said blower head, by said shroud and a periphery of one of said components;
- said blower head having a defined blower opening oriented parallel to and extending along substantially the entire width dimension;
- (d) air pressurizing means connected to said blower head for introducing pressurized air into said blower head for discharging said pressurized air through said blower opening;
- (e) a suction head situated in a radial space bounded, at opposite sides of the suction head, by said shroud and a periphery of one of said components;
- said suction head having a defined suction opening oriented parallel to and extending along substantially the entire width dimension;
- said suction head being spaced from said blower head transversely to said width dimension;
- said blower opening being directed towards said suction head;
- and
- (f) air withdrawing means connected to said suction head for withdrawing air, flowing in said space from said blower head, through said suction opening.
