Abstract
The invention provides a creel for feeding slivers (21) of fibers to a processing machine (10), comprising a bank of feed stations (13c) to (13i) and two reserve feed stations (13a) (13b). Upon disruption at any feed station in the bank, a reserve feed station comes into operation and is moved into the bank of feed stations, while the station where the feed was interrupted is moved to a reserve feed station position. Movement of the stations is effected by moving a carriage at a station, which includes feed rollers, sensors etc. to the required positions. The carriages are moved along a first rail in an upstream position and a second rail in a downstream position and are transverable between these rails.
Claims13
A creel comprising a plurality of feed stations, arranged in a bank, for feeding slivers of fibres to a sliver processing machine, a reserve feed station for feeding a reserve sliver to the machine upon disruption of sliver feed at any station, means for removing the station where feed is interrupted from the bank of feed stations, means for entering the reserve feed station, upon operation thereof, into the bank of feed stations, each of said feed stations including a carriage member for drawing a sliver by means of rollers or other feed means, from a sliver reservoir and delivering the sliver to a pathway leading to the processing machine, the carriage members being movable for purposes of entering or removing a station from the bank of feed stations, said carriage members being movable upstream and downstream relative to the processing machine such movement being respectively towards the station most remote from the machine and towards the station in closest proximity to the machine, so that in the event of feed at a station being interrupted, its carriage member can be moved downstream from the bank of stations to a reserve station position while the carriage members downstream therefrom and the reserve station carriage member can be moved upstream to refill the bank.
The creel according to claim 6 wherein drive means in the form of a moving chain or the like is provided for moving the carriage members along the tracks.
A creel comprising a plurality of feed stations arranged in a bank for feeding slivers of fibres to a sliver processing machine, each of said feed stations including a carriage member having feed means for drawing a sliver from a sliver reservoir and delivering the sliver to a pathway leading to the processing machine, sensor means being operatively interconnected to said feed stations for detecting a disruption of sliver feed at any of the feed stations, removing means operatively interconnected to said feed stations for removing the feed station wherein a disruption of sliver feed occurs upon detection of the disruption, further means for entering a reserve feed station into the bank of feed stations upon removal of the feed station wherein a disruption occurs, said reserve feed station being activated to feed a sliver of fibre to the sliver processing machine so as to provide a full compliment of feed stations.
