  • the gist of the present invention resides in an opening and stacking method which comprises plucking olf fibres uniformly from the bottom of bales and then, after first storing the respective fibres in their reserve boxes, laying the fibres in sheets or mats one on top of another according to the prescribed blending rati-o and thereafter feeding the fibre sheet to the next following process.
  • the invention is also directed to an apparatus for opening and stacking fibre from bales by which the hereinabove described method is carried out, the apparatus comprising a combination of a plurality of plucking mechanisms and a rack for mounting the fibre bales which are to have fibre plucked therefrom by means of the plucking mechanisms, said rack being capable of effecting the reciprocative movements of the fibre bales in the longitudinal as well as transverse directions above the plucking mechanisms, conveying means disposed below the several plucking mechanisms for feeding the plucked ofi libres to their corresponding reserve boxes, and a conveying means disposed below the several reserve boxes and adapted to lay one on top of another the fibres in sheets or mats delivered from said reserve boxes.
  • the rack is provided with a plurality lof grid rollers disposed in parallel and rotating in the same direction first in a clockwise and then in a counterclockwise direction, the purpose being to move the fibre bales mounted on the rack reciprocally.
  • the plu-cking mechanism is positioned between the foregoing grid rollers and consists of a plurality of plucking saws or blades installed on one or two rotatable plucking rollers shafts that move relative to the fibre bale.
  • an object of this invention is to provide a method of plucking different fibres separately from a plurality of fibre bales and feeding the fibres necessary for blending to reserve boxes for the purpose of stacking the same.
  • Another object of the invention is to provide an apparatus which plucks .off different fibres separately from the bottom of a plurality of fibre bales and, after conveying the plucked off fibres to their separate reserve boxes, feeds the fibres of the reserve boxes to the next processing step in accordance with a prescribed blending ratio.
