Abstract:
The invention relates to a method for manufacturing a mineral fiber-containing composite and the novel mineral fiber-containing element produced by that method.
Abstract:
A throttle valve is provided within a discharge air duct located adjacent a fiber duct receiving a fiber laden air stream. The throttle valve cooperates with a stop in a lowered position to form a gap to allow a minimal air flow therethrough. In addition, a weight is provided on an arm attached to the throttle valve for pivoting therewith. The weight is disposed to counterbalance a substantial portion of the weight of the flap valve in the raised position of the valve so that the air flow maintains the valve in the open condition.
Abstract:
An apparatus for depositing loose materials, such as insulation or fireproofing in worksite areas, may be used for depositing a single or premixed loose material. Alternatively, the apparatus may be used both for combining two constituent loose materials to form a composite loose material and for depositing the composite loose material in a worksite area. The apparatus includes a separate hopper or bin for each of the constituent loose materials. Each hopper is operatively connected to a single loose material combining channel for supplying their respective constituent loose material for forming the composite loose material immediately before it is deposited in the worksite area. A single motor is used for supplying both constituent loose materials to the combining channel. The ratio of constituent loose materials in the composite loose material may be changed by replacing an easily accessible gear used in driving an auger for extracting the constituent loose material from one of the hoppers. In replacing this gear with a different sized gear, and thereby changing the ratio of constituent loose materials in the composite loose material, the hopper having the auger may be rotated to disengage the gear from a drive train, the gear is then replaced, and the hopper is rotated in the opposite direction until the replacement gear engages the drive train.
Abstract:
This invention relates to the creation of a different styled batt from tufts of fiber for delivery to textile machinery. In particular, the batt formed in the style of this invention is particularly suited for delivery to a carding machine. Carding machines are able to more fully utilize fiber processing capacity with lower risk of becoming overloaded because the tufts are less able to be pulled out of the batt intact but are held back allowing for the lickerin roll or other feed arrangement to pull fiber out of the batt in a more continuous and uniform manner.
Abstract:
An apparatus for feeding fiber tufts to a fiber processing machine, including a fiber reserve device; an intake device drawing fiber tufts from the fiber reserve device; a fiber opening device adjoining the intake device and being arranged for receiving fiber tufts from the intake device; and a substantially horizontally oriented feed chute having an inlet connected to the outlet of the fiber reserve device. The fiber opening device advances fiber tufts into the inlet of the feed chute. The apparatus further includes a blower for introducing an air stream into the feed chute through the inlet thereof. The feed chute has an outlet for discharging fiber tufts therefrom and air outlet openings in the outlet zone for discharging air from the feed chute.
Abstract:
A fiber storing device includes an inlet for charging the device with fiber material and an outlet for withdrawing fiber material therefrom. The fiber storing device is associated with an apparatus for determining the fill level of fiber material in the storing device. The apparatus has an optical device which comprises a light emitter and a light detector and which is situated above an expected maximum fill level of the fiber material. The light emitter is arranged to direct, from above, a light beam onto an upper face of the fiber material and the light detector is arranged to receive a light beam reflected from the upper face of the fiber material.
Abstract:
A fiber feeder apparatus includes a driven endless supply conveyor belt having a coneveying surface for supporting a fiber pile and an endless spiked lattice arranged at one end of the supply conveyor belt and extending at an upward inclination therefrom. The spiked lattice has spikes arranged to penetrate into the fiber pile for effecting removal of fibers from the fiber pile. The supply conveyor belt is driven such that the fiber pile is being fed by the conveying surface into contact with the spikes. There is further provided a control device which is connected to the drive of the supply conveyor belt for effecting a nonuniform driving thereof.
Abstract:
Apparatus for cleaning textile fibers such as cotton, etc. is disclosed wherein the fibers are conveyed by an air current to an opening roller cooperating with a grate, and the transport air is separated at a feed box. The separated air (17) serves for discharging contaminants accumulating in a space (9, 11) beneath the cleaning grate (8). The opening roller (7) may be provided with a toothed wire (20) whose teeth have a relatively acute top rake (22).
Abstract:
An apparatus for feeding a fiber lap to a card, includes an upper reserve chute having an upper end through which fiber material is introduced into the apparatus, a feed roller situated at a lower end of the reserve chute and arranged for withdrawing fiber material therefrom; a feed chute having an upper end situated adjacent to the lower end of the reserve chute; and an opening roller situated in a space between the lower end of the reserve chute and the upper end of the feed chute. The opening roller is arranged under the feed roller to receive fiber material therefrom and to advance the fiber material into the feed chute through the upper end thereof. There are further provided delivery rollers at a lower end of the feed chute for withdrawing fiber material therefrom as a fiber lap; and an air circulating arrangement for introducing a compressing air stream through the upper end of the feed chute, driving the air stream through the feed chute to compress fiber material therein and withdrawing air from openings in a lower portion of the feed chute. The feed roller and the opening roller are rotated simultaneously in opposite directions relative to one another and the compressing air stream is guided adjacent the opening roller codirectionally with the rotary direction thereof.
Abstract:
An arrangement for pneumatically transporting fiber material flocks through respective chutes to individual carding machines includes a duct which bounds an internal passage that communicates with the chutes, the chutes extending downwardly from the duct. A plurality of control elements is arranged in the passage, respective two of such control elements being situated between each adjacent two of the chutes. Each of the control elements has a substantially plate-shaped control member which is pivotally mounted at the bottom region of the duct, and a block member that extends substantially at a right angle to the control member remotely from the pivot axis and extends toward and into the respective chute. The control element can be pivoted into and arrested in any selected pivoted position, including a closed position in which the block member thereof substantially completely prevents the flow of the transporting medium past the same. The transporting medium carrying the flocks is introduced into either one or into both of the ends of the passage, and the positions of the control elements are so adjusted as to obtain flow speeds upstream of the respective chutes in the range substantially between 2 and 10 m/s; the transporting medium volume can also be adjusted toward this goal. Those of the control elements which are situated between two adjacent chutes may be mounted on a common pivot axle.
