Embodiment Construction

[0024] refer to Figure 1-6 An embodiment of the present invention will be described below. figure 1 is a partial sectional side view showing one side of a drafting device and a fiber bundle bundling device. Fig. 2a is a schematic view of the fiber bundling device viewed in the direction of fiber withdrawal at the nip point (as seen from the front side with respect to the direction of movement of a fiber bundle in the drafting device). image 3 yes figure 1 A partially enlarged view of .

[0025] Such as figure 1 As shown, the drafting device 11 as a drafting section is a three-row structure equipped with front bottom rollers 12, middle bottom rollers 13 and rear bottom rollers 14. The front bottom roller 12 is supported at a predetermined position on a roller support 15 constituting a machine bottom frame, and the middle and rear bottom rollers 13 and 14 are supported by support brackets 13a and 14a fastened to the roller support 15. center to allow position adjustmen...

Abstract

A fiber bundle collecting device (30) is equipped with a send-out portion (31) provided on the downstream side of a final send-out roller pair of a drafting device, and a suction pipe (32) having a slide surface equipped with a suction hole (32a) formed so as to extend on the upstream side of the nip point of the send-out portion (31) with respect to the direction in which the fiber bundle moves. On the opposite side of the suction pipe (32), there is provided a wrapping member (33), with a bottom nip roller (35a) for forming the send-out portion (31) being therebetween. An air-permeable apron (34) is wrapped around the suction pipe (32), the wrapping member (33), and the bottom nip roller (35a). The wrapping member (33) is provided as a component separate from the suction pipe (32) in order to increase the fleece angle. The suction pipe (32) is connected to a duct through a connection pipe (48), with a suction device being connected to the duct.

Description

technical field [0001] The present invention relates to a fiber bundle bundling device of a spinning machine, and more particularly to a fiber bundle bundle device arranged on the downstream side of a drafting device (drafting section) of a spinning machine and adapted to collect fibers drawn by the drafting device. The fiber bundle binding device of the spinning machine of the fiber bundle. Background technique [0002] Generally, JP07-238425A discloses a fiber bundle bundling device of this type, wherein such as Figure 7 As shown, on the downstream side of a pair of final rollers 61 constituting a drafting device, a pair of delivery rollers 63 are provided with a perforated apron 62 provided with a device for applying a suction air flow to the perforated holes. Air suction of the conveying surface of the apron 62 . In this fiber bundle bundling device, a suction air flow is applied to the conveying surface of the perforated apron 62 through a suction slot formed in an ap...
