Improvements in and relating to the treatment of threads

摘要

The apparatus of the parent Specification, which liquid treats cellulose threads &c. regenerated from viscose, is provided with a modified baffle which comprises a horizontal thread supporting bar 2 and two thread guides 3 screwed one to each side of the bar 2 and having inverted L-shaped arms 5. The uprights 6 of the arms 5 lie directly one behind the other and have portions 7 projecting in opposite directions and overlapping to define thread guide holes 8, the ends of the portions 7 being bent outwardly to form threading-up slits 9. In Fig. 2 (not shown) a number of such baffles are fitted into a trough of the parent Specification and each successive baffle is offset by one thread space so as to ensure that each thread is laterally confined to its path by arms 5 in every third baffle.ALSO: The apparatus of the parent Specification, for the liquid treatment of cellulose threads &c. regenerated from viscose, is provided with a modified baffle which comprises a horizontal thread-supporting bar 2 and two thread guides 3 screwed one to each side of the bar 2 and having inverted L-shaped arms 5.
