Abstract:
The invention relates to a fiber processing system for opening and mixing fiber material, with a multiple number of bale openers (2) for opening fiber bales (FB) and conveying devices (4a, 4b; 14a, 14b) downstream of the bale openers (2) for mixing and conveying the opened fiber material to a downstream processing device (10), for example a mixing chamber or a carding feed. The device in accordance with the invention is characterized in that the bale openers (2) are divided into at least two opener groups (3a, 3b; 13a, 13b), each of which produces a fiber mixture (M1, M2), and that each opener group (3a, 3b; 13a, 13b) is allocated with a conveying device (4a, 4b; 14a, 14b), whereas the conveying devices (4a, 4b; 14a, 14b) are designed and arranged in such a manner that the respective fiber mixture (M1, M2) is transported away in relation to the associated opener group (3a, 3b; 13a, 13b) in different directions (R1, R2; R1′, R2′) and the fiber mixtures (M1, M2) are combined before or in the processing device (10) into an overall fiber mixture (GM). Likewise, the invention relates to a method for opening and mixing fiber material in a fiber processing system.
Abstract:
A yarn producing apparatus produces carbon nanotube (CNT) yarn by aggregating CNT fibers. A substrate support supports a CNT forming substrate, a winding unit 7 continuously draws the CNT fibers, a yarn producing unit aggregates the CNT fibers, and a substrate replacing mechanism replaces the carbon nanotube forming substrate supported on the substrate support with another carbon nanotube forming substrate.
Abstract:
In a device on a spinning room preparation machine, for example a fiber flock feeder, carding machine, cleaner or the like, for supplying and/or discharging fiber material, a tray-like guide element having a guide surface co-operates with at least one conveyor roll located opposite, the fiber material being guided towards and along the guide surface. In order to provide a simple way of supplying and/or discharging fiber material without undesirable adhesion of fibers, the guide element located opposite the at least one conveyor roll is arranged to be set in vibration by at least one actuator.
Abstract:
In an apparatus in a spinning room for transporting a can-less fibre sliver package between a sliver-delivering spinning machine, for example a draw frame, or a storage means and a further processing device or a further storage means, having a support for receiving the can-less fibre sliver package, the support being substantially unenclosed, the support and the can-less fibre sliver package are transportable in common. In order to effect simple transport of the can-less fibre sliver package, the support for receiving the at least one fibre sliver package can be brought to the sliver-delivering spinning machine or to the storage means and, after the package has been received, the support, together with the stably positioned fibre sliver package, can be supplied to the further processing device or to the further storage means.
Abstract:
In an apparatus in a spinning mill for transporting a can-less fibre sliver package between a sliver-delivering spinning machine, for example a draw frame, or a storage means and a further processing device or a further storage means, having a support for receiving the can-less fibre sliver package, the support being substantially unenclosed, the support and the can-less fibre sliver package are transportable in common. In order to effect simple transport of the can-less fibre sliver package, there is a transport device for common transport of the support and at least one stably positioned fibre sliver package, the transport device being track-guided or freely movable.
Abstract:
An apparatus on a spinning machine for depositing fibre sliver. The apparatus comprises a delivery device comprising a coiler plate adapted to deliver fibre sliver in the form of a can-less fibre sliver package. The apparatus also comprises a substantially planar receiving support surface onto which the fibre sliver is deposited, the receiving support surface adapted to move back and forth in a deposition area with respect to the delivery device through a substantially horizontal stroke. The receiving support surface is also adapted to move away from the delivery device in a substantially vertical stroke during delivery of the fibre sliver. The delivery device and the receiving support surface are both adapted to remain in contact with the fibre sliver as it is deposited in the form of a can-less fibre sliver package, such that the fibre sliver package is stabilized during the substantially horizontal stroke and during lowering of the receiving support surface.
Abstract:
This machine includes a moving condenser and an undercarriage having a solid plate confronting a part of the perimeter of the condenser. The condenser may be a rotating foraminous screen, or an endless foraminous belt. There is a duct inside the condenser, through which air is sucked to draw fibers onto the screen, and an adjustable baffle for determining the effective area of this duct. Fibers are sucked into the space between the plate and condenser by the air flowing through the condenser and compacted into a web by the moving condenser. In one embodiment of the invention an air intake box and an adjustable flap increase the stripping action on the pins of an apron in a feed hopper to deliver fibers between the undercarriage and condenser. In this embodiment also means is provided for varying the throat opening of the air bridge which carries the fibers from this apron between undercarriage and condenser. In another embodiment of the invention, to control the mat thickness the undercarriage is bodily adjustable relative to the condenser which here is an endless screen belt.
Abstract:
A procedure for processing staple fibers into uniform batts by the use of a water spray to wet the fibers and a compression device to depress the fibers more densely into batt form.
Abstract:
A device having a pivotally mounted load sensing means and a motor actuating means responsive to movement of the load sensing means is provided. The device regulates the feeding of material to a processing machine. The motor actuating means is for switching on and off a flow of material to be fed to the processing machine. The load sensing means is responsive to the weight of material flowing into a supply container for subsequent feeding to the processing machine. The load sensing means is adapted to move about its pivotal axis when material in the supply container reaches a predetermined level. A specific embodiment of this regulating device includes a mechanism for feeding spinning material or the like to a processing machine such as a carding machine, carders or the like.
Abstract:
The fiber arrangement removed from the feed chute is monitored down stream of the chute to detect deviations in thickness or mass of the fiber arrangement from a preset value so that the deviations are used to cause an increase or decrease of the pneumatic pressure acting on the top of the fiber flock column. The change in pressure results in a change in the amount of pressure drop to which the column is subjected so that the degree of condensation of the column is likewise changed to eliminate or reduce further deviations.
