摘要:
A drawing machine having a drawing zone (8) for drawing slivers (2), and a plurality of flyers (14) for winding the slivers on to bobbins (16), is made compact by arranging the flyers substantially longitudinally of the paths of the slivers through the drawing zone, e.g. in echelon formation with respect to the sliver paths.

A yarn spinning, twisting or doubling machine having bobbin doffing and donning apparatus for the spindles of the machine, the apparatus comprising bobbin conveying means (4) extending along and above a row of spindles, a series of bobbin grippers (16) spaced at the same pitch as the spindles, each gripper being mounted for vertical movement between its respective spindle and the conveyor (4), each gripper being designed to hold or grip a bobbin at a point beyond one end of a package (125) wound on the bobbin so that the grippers can lift the wound bobbin from its spindle for engagement by means on the conveyor and then release the bobbin for subsequent removal, or grip an empty bobbin (64) on the conveyor and move it to its respective spindle and control means operable to move the conveyor after it has received the full doffed bobbins and to bring empty bobbins into line with the spindles so that the grippers can place empty bobbins on the spindles. This equipment enables the bobbins to be accurately positioned on the spindles and removed from the spindles without the problems which arise from the use of inflatable sleeves.

A bundles of fibres 32 suspended from a holder 34 is combed by co-operating arrays of pins 31,33 which are driven around closed paths defined by rollers 37, 38, 39,35,40,41. When the arrays are moved together, they form a substantially vertical working reach over which the pins in the arrays are opposed as they move in a downward direction alongside one another in order to comb the fibres. The arrays are pivoted about the lower rollers 35,37, and mechanism including cams 50, followers 51 and links 54 periodically adjusts the spacing between the co-operating arrays of pins in the working reach so as to increase the gap between them, as shown. The bundle of fibres is moved into the zone of the working reach at a time when the gap is increased and when the arrays of pins come together, combing takes place. The arrays then move apart again and a fresh bundle of fibres is introduced.

Textile processing apparatus including: at a first station, one or more machines having a plurality of spindles, for use in winding drawn slivers on to bobbins; at a second station, a plurality of spinning machines (a-h) and, if desired, bobbin reservoirs (39a-39h) therefor; means for indicating the present or future requirement for a type of sliver to be spun; an endless conveyor (31) for the transport of the bobbins (6) between the first station and the second station; a variable reference indicator on each bobbin; means which sets each indicator as an identification of the type of sliver wound on that bobbin; detection means (94a, 94b) which can detect the transport of indicator-identified bobbins; and at the second station, bobbin displacement means (35a-35h) which can act in association with the detection means (33a-33h) so as selectively to transfer bobbins from the conveyor towards spinning machines, or reservoirs (39a-39h) therefor, for which the types of sliver on the bobbins are required.
