Abstract
An apparatus for mixing fiber tufts includes a first conveyor for accommodating thereon a row of fiber bales; a bale opener for travelling along the row of fiber bales and removing fiber tufts sequentially from the fiber bales; a storage system for storing a plurality of fiber bales each containing fiber of predetermined properties; a selecting device for selecting fiber bales of desired properties from the fiber bales accommodated in the storage system; and a second conveyor for sequentially advancing the selected fiber bales from the storage system to the first conveyor for complementing the row of fiber bales accommodated on the first conveyor for obtaining a series of fiber bales thereon having preselected, determined properties.
Claims10
An apparatus for mixing fiber tufts, comprising
- (a) a first conveyor means for accommodating thereon a row of fiber bales;
- (b) bale opener means for travelling along the row of fiber bales and removing fiber tufts sequentially from the fiber bales;
- (c) storing means for storing a plurality of fiber bales each containing fiber of predetermined properties;
- (d) selecting means for selecting fiber bales of desired properties from the fiber bales in said storing means;
- and
- (e) a second conveyor means for sequentially advancing the selected fiber bales from said storing means to said first conveyor means for complementing said row of fiber bales accommodated on said first conveyor means for obtaining a series of fiber bales thereon having preselected, determined properties.
A method of removing fiber tufts from fiber bales, comprising the following steps:
- (a) establishing identifiable groups of fiber bales, wherein the fiber bales within each group have identical, determined fiber properties and wherein the properties are different in each group;
- (b) composing a row of fiber bales of predetermined, selected fiber properties;
- (c) detaching fiber tufts in sequence from the fiber bales of said row;
- (d) variably selecting further fiber bales from selected said groups, including the step of determining a limit interval for the fiber properties of each group;
- and
- (e) consecutively adding the further fiber bales to said row, including the step of adding a fiber bale of different property when said limit is exceeded.
