Title: Preparation of roving from carding engine web - in self threading machine rectifying variations for spinning frame
IPC: D01G/
Filed: 1977-07-18
Granted: 1986-02-10
Abstract: In the parent patent a small and compact device converts a web from a card into a roving for the spinning frame, by passing it, bundled together through a conical guide into the nip of a first pair of drafting rollers and on to a second pair of drafting rollers. From the second pair the roving is guided through a second funnel between sensitive measuring rollers regulating the speeds of the drafting rollers and thence to the coiler. In this addn. the device for feeding, drawing and measuring a roving of textile fibres has a guide with a conical bore for feeding a web of fibres from the card to a first pair of rollers. A second pair of draw rollers are positioned downstream from the first pair, and a calibrating detail fits neatly into the spaced between the first and the second pair of rollers, and having an inlet close to the nip between the first pair of rollers and an outlet close to the nip between the second pair of rollers. Mechanisms for driving the first and second pairs of rollers at different speeds for drafting the roving, the rollers of the second pair having respectively a groove and a rib working together so that they act as measuring rollers as well as drafting rollers. A lever pivoting on the frame posns. the calibrator funnel between the pairs of rollers, and mechanisms are provided to open and close the rollers of each pair as well as to alter their relative posns. A single roving can not only be formed from the carded web, but it can also be drawn accurately as it is made in a closed loop system with a much simpler layout.

Apparatus for effecting the classification of particles by flotation comprises a cell a containing a series of zig-zag guide walls 21 to form a number of zig-zag ducts, diffusers 17 arranged below the cell a to conduct a suspension of solid concentrated particles in a finely dispersed mixture of air bubbles to the ducts and to reduce the entry speed of the suspension into the ducts and irregularly arcuate guide wall portions 45 arranged to produce eddy zones at the bends in the zig-zag ducts. As shown in Fig. 1b an aqueous suspension of a material passes from a rod mill to a stirring mixer where reagents are added and then to a pre-mixing chamber 4 which is provided with internal fittings 5 which distribute air into the suspension, a supply duct 6 opening into the chamber 4 and serving for the introduction of air and a mist of a foaming reagent formed by an atomising device 7. The suspension passes to a stirring device which includes an annular space 10 from which the suspension passes through a number of outlet openings 11. Coarse particles coming against the wall of the space 10 are passed by centrifugal force through ducts 12 for repeated treatment. The suspension passes through flexible ducts 16 to the diffusers 17, oversize particles being separated and fed back through hoses 18 into a dock 19 for further treatment. Each of the diffusers opens into the zig-zag ducts the zigzag walls 21 ending in the upper part of cell a at different levels so that the suspension is directed at right angles and moves over a sedimentation device 22 the tapering outlet ducts of which are connected by means of flexible pipes to an overflow 25 the height of which can be adjusted by a handwheel 21.
