Abstract
A method and a device for opening and dosing fiber feeds the fiber material via a feeding shaft of an opening device. The fiber material is processed in a first opening step of a dosing opener and is fed without an interconnecting pneumatic means to the feeding shaft of a second opening step. A large-volume feeding shaft has been placed before the first opening device from which the fiber material is delivered to a feeding shaft with a considerably smaller volume that delivers the fiber material to a second opening device. Both opening devices and their associated feeding shafts are placed on top of one other.
Claims15
A method of opening and dosing fiber material, comprising:
- feeding fiber material that has been opened or mixed in a first processing equipment to a dosing opener;
- from the dosing opener, delivering the fiber material to a flock feeder of a carding machine or other downstream processing equipment;
- in the dosing opener, processing the fiber material through a feeding shaft of a first opening step and delivering the fiber material from the first opening step directly into a feeding shaft of a second opening step without pneumatic conveyance between the first and second opening steps;
- and
- wherein the fiber material has essentially the same throughput in the first and second opening steps but is opened more finely in the second opening step than in the first opening step.
A device for opening and dosing fiber material in a fiber processing system wherein fiber material is feed to said device from processing equipment that opened or mixed the fiber material, said device comprising:
- a first feeding shaft disposed to receive fiber material from the upstream processing equipment;
- a first opening device disposed to receive fiber material directly from said first feeding shaft;
- a second feeding shaft disposed under said first opening device to receive fiber material directly from said first opening device, said first feed shaft having a volume that is at least twice a volume of said second feeding shaft;
- a second opening device disposed under said second feeding shaft to receive fiber material directly from said second feeding shaft;
- and
- said first and second opening devices arranged one above the other without intervening pneumatic conveyance of the fiber material between said opening devices.
