Figure 3 is a side view of a further form of apparatus in which the drying belt serves also as the open support from which the tow is withdrawn.
Referring to Figures 1 and 2 of the drawings, a tow I is laid in convolutions 2 on a travelling belt 3 which carries the convolutions of tow through a drying chamber 4. The dried tow is then transferred from the belt 3 to a second conveyor formed by two parallel moving belts 5 and 6, both supported and driven by rollers 1 and 8, with a gap 9 between the belts. As shown, the belts 5 and 6 are slightly lower than the belt 3 in order to assist in the transfer of the dry tow from belt 3 to belts 5 and 6. After the convolutions 2 of tow have been carried forward by belts 5 and 6 for a distance at least suflicient to cool the tow, the end of the moving tow is withdrawn substantially vertically downwards through the gap 9, round the transverse rod ID and then to a crossball collecting device Il. The belt 3 is preferably a woven wire belt such as is normally employed for drying tow. When using two belts 5 and 6 as described, the tow is withdrawn from each of the belts alternately so that the direction in which the tow is pulled on the belts is continually changing.
The driving rollers 1 and 6 are preferably geared to the drive for the belt 3 so that all the belts 3, 5 and 6 are moved at the same speed.
In the apparatus shown in Figure 3 a single conveyor is used, the apparatus otherwise being the same as shown in Figures 1 and 2 and like reference numerals are included to show the corresponding parts. As shown in Figure 3 the tow I is fed in convolutions 2 on to a conveyor 3 which consists of two parallel belts preferably constructed in the same manner as the belts 5 and 6 of Figure 2; in this case therefore the tow is withdrawn substantially vertically downwards through the opening in the support 3', round the guide rod I0 and thence to the collecting device l l.
What I claim is:
1. In a process for drying a continuous tow of artificial bres by feeding wet tow in convolutions on to a travelling support, conveying the convolutions of tow whilst on the support through at least one drying chamber and passing the dry tow at a rate substantially equal to the rate of veyor belts lying side by side whilst the mass is supported and being conveyed on said belts.
2. Apparatus for drying a continuous tow of artificial fibres comprising in combination, at least one drying chamber, a travelling support lor conveying the tow through the said drying chamber and having an opening through which the tow can pass downwardly, a guide situated beneath the support, and draw-off mechanism for withdrawing the tow at the end of thedrying operation through said opening in said support and into contact with said guide.
3. Apparatus for drying a continuous tow of artificial fibres comprising in combination at least one drying chamber, a travelling support for conveyingthe tow through the said drying chamber, a second travelling support arranged at the end of the first travelling support for receiving the dried tow and having an opening through which the tow can pass downwardly, a guide situated beneath said second support, and draw-off mechanism for withdrawing the dried tow through said opening in said second support and into contact with said guide.
4. Apparatus as claimed in claim 3 wherein the second travelling support comprises two endless conveyor belts lying side by side with a gap between them, through which gap the tow may be withdrawn substantially vertically downwards.
5. In a process for drying a continuous tow of artificial fibres by feeding wet tow in convolutions on to a travelling support, conveying the convolu tions of wet tow through a drying chamber on a travelling support and passing the dry tow at a rate substantially equal to the rate of feed to a collecting device and the steps of passing the tow when dry on to a second moving support having an opening and withdrawing the dried tow substantially vertically downward through said opening from the underside of the mass of convolutions whilst the mass is supported and being conveyed.
