The machines for rove (roving frames) are designated by the size of the bobbin upon which the rove is wound, e.g.
"The Jute Industry: From Seed to Finished Cloth" by T. Woodhouse and P. Kilgour
As in the slubber, intermediate, and roving frames, the rove is taken from two bobbins for one spindle.
"Textiles" by William H. Dooley
Imagine a bobbin full of roving standing on a frame.
"Makers of Many Things" by Eva March Tappan
The "set" of machines just named are usually known by the names "Slubber," "Intermediate or Second Slubber," and "Roving" Frames.
"The Story of the Cotton Plant" by Frederick Wilkinson
Too much twist in roving makes bad yarn, and spoils the top rolls on spinning frames.
"Instruction book on ring spinning" by Francis L. Lincoln
As the yarns still need to be twisted, they are passed through a roving frame similar to a drawing frame.
"Inventions in the Century" by William Henry Doolittle
SLUBBING, INTERMEDIATE AND ROVING FRAMES.
"Illustrated Catalogue of Cotton Machinery" by Howard & Bullough American Machine Company, Ltd.
The rove yarn is now ready for the spinning frame, where a further draft of about eight is given.
"Encyclopaedia Britannica, 11th Edition, Volume 15, Slice 6" by Various
Amazement chill'd the shepherd's frame,
To think Bridgewater's honour'd name
Should grace his rustic cell;
That she, on all whose motions wait
Distinction, titles, rank, and state,
Should rove where shepherds dwell.
"A Pastoral Ode. To the Hon. Sir Richard Lyttleton" by William Shenstone
