Abstract
In a plant for processing textile fibers, the fine cleaning is effected at a point at which the stream of fiber material already has been subdivided (e.g. for the subsequent carding process), e.g. in the card filling chute. The cleaning device comprises at least one separating element arranged above the transporting roll. The trash eliminating system includes a system for eliminating material separated from the zone of the roll.
Claims11
A supply system for supplying fiber material to a textile carding machine, comprising:
- a filling chute configured with said card machine, said filling chute comprising an upper supply chute section and a lower reserve chute section;
- an opening roller disposed within said filling chute between said upper supply chute section and said lower reserve chute section;
- a feed roll disposed relative to said opening roller so that a takeover point for fiber material transferred from said feed roll to said opening roller lies before and below a highest circumferential point of said opening roller in the direction of rotation thereof;
- nip feed structure disposed relative to the circumference of said feed roll so as to define a nip feed arrangement for the fiber material before said takeover point in a direction of rotation of said opening roll;
- at least two trash eliminating devices disposed above a horizontal plane through a rotational axis of said opening roller and after said feed roll and said takeover point in the direction of rotation of said opening roller, a first one of said trash eliminatng devices disposed adjacent said feed roll in the direction of rotation of said opening roller, said eliminating devices disposed relative to a circumferential surface of said opening roller so as to remove trash and debris from fiber material carried by said opening roller and to convey said trash and debris tangentially away from said opening roller;
- and
- said trash eliminating devices further comprising a pneumatic elimination system disposed to substantially immediately carry away said removed trash and debris such that said trash and debris is prevented from falling and collecting below said opening roller.

- a filling chute configured with said card machine, said filling chute comprising an upper supply chute section and a lower reserve chute section;
- an opening roller disposed within said filling chute between said upper supply chute section and said lower reserve chute section;
- feed roll disposed relative said opening roller so that a takeover point for fiber material transformed from said feed roll to said opening roller lies before and below a highest circumferential point of said opening roller in the direction of rotation thereof;
- at least two trash eliminating devices disposed above a horizontal plane through a rotational axis of said opening roller and after said feed roll and said takeover point in the direction of rotation of said opening roller, said eliminating devices disposed relative to a circumferential surface of said opening roller so as to remove trash and debris from fiber material carried by said opening roller and to convey said trash and debris tangentially away from said opening roller;
- said trash eliminating devices further comprising a pneumati elimination system disposed to substantially immediately carry away said removed trash and debris such that said trash and debris is prevented from falling and collecting below said opening roller;
- and
- wherein said air conveying system draws air from said deflection zone and through said fiber batt forming device, and re-circulates the air stream back to said deflection zone.

A supply system for supplying fiber material to a textile carding machine, comprising:
- a filling chute configured with said card machine, said filling chute comprising an upper supply chute section and a lower reserve chute section;
- a cleaning module disposed within said feed chute, said cleaning module further comprising:
- an opening roller disposed within said filling chute between said upper supply chute section and said lower reserve chute section;
- a feed roll disposed relative to said opening roller to define a takeover point for fiber material transferred from said feed roll to said opening roller;
- at least one trash eliminating device disposed above a horizontal plane through a rotational axis of said opening roller, said eliminating device disposed relative to a circumferential surface of said opening roller so as to remove trash and debris from fiber material carried by said opening roller and to convey said trash and debris tangentially away from said opening roller;
- and
- said trash eliminating device further comprising a pneumatic elimination system disposed to substantially immediately carry away said removed trash and debris such that said trash and debris is prevented from falling and collecting below said opening roller;
- a base frame supporting and determining the position of said cleaning module, said base frame comprising lateral walls and cross ties disposed between said lateral walls, said lateral walls having a thickness to support maintenance and positioning of said cleaning module;
- and columns coordinated with each said lateral wall, said columns formed from sheet metal clamped between said lateral walls, said cross ties rigidly connected to said lateral walls.
