This invention relatesV generally to the art Y' of making binder and other twines and has especial relation to means for preparing-'the fiber or sliver used inthe manufacture of twines, an object being to provide a drawing head which will befunaffected by atmospheric draw and practically eliminate variation in the finished product. Y
Another object of the invention is the pro- Y vision of adrawin'gl head which will not pick vup the fiber and carry it around the rolls, which frequently occurs with the luse of leather aprons, while 'uniformity of'tension is maintained Without frequent adj ustrnent asis necessarywhen leather aprons are used.
i Another object ofthe invention is the pro--.
vision ofa dra-wing head which, in addition to the above and other advantages, is constructed so that the number of bearings usually required for leather-apron heads are materially reduced and the power necessary for operation will be likewise reduced.
With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the 'appendedA claims.
In the drawings Figure l is a side elevation of a drawing head constructed in accordance with the invention and mounted in position for use, a
fragmentary portion of a finishing machine being illustrated.

leather which pass around spaced rolls.
These belts however are sensitive to' atmospliericV conditions sothat frequent adjustment isnecessary to maintain any uniformity ofLdra'w. In addition, the belts aresubject to great wear and must frequently vbevreplaced.' Further, these leather aprons pick up the fiber and carry it around. 'l
The drawing head of the present invention iron) A'upper roll 13 anda pair of spacedk lowerrolls 14 which arel also preferablyiof cast iron. The rolls 13 and 14 are preferably fluted and the lower rollsare relatively small in diameter. f' The lower rolls 14 are mounted in suitabl bearings provided ina base 15 which isin turn mounted upon the frame 10, while the .upper roll is mounted in adjustable bearings 16 which are slidable in spacedV standards 17 rising from thebaselQ The-bearings 16 are yieldingly forced downward bymeans of springs 18 so Vthat a yielding contact is provided betweenthe rolls 13 and 14. The tension of the springs 18 may be regulated by adjusting screws 19.
The shafts of the rolls 14 have mounted y kthereon gears 2O which are engaged byan v idler gear 21, while one of theshafts of the rolls 14 hasmounted thereon a driving pinv ion 22 which operates the gear train 23 forming a part of the mechanism of the fine ishing machine.
` Each of the rolls 14 is provided with a wiper which includes an inverted substantially U-shaped frame 27 whose opposite side This guide comprises spaced supporting arms are provided withelongated slots 28.
Bolts29 pass through these slots and engage the frame 1() so thatthe frames 27 will-be l0 in brackets secured tothe trarne- 10, the
mounted forv vertical sliding movement. Mounted upon each of the frames 27Y is a wiper element 30 which engages one of the -'ment is-yieldingly itorcedv into engagement krolls 141- andprevents the fiber or sliver from passing around these rolls. The wiper elewith the rolls 14: by coiled springs 3l which surround bolts or studs 32 extending,` down'- wardlyV from the frames 27. Thebolts; or studs 32 are mountedl for sliding movement springs 31 ybeing` interposed between these brackets andtlieirames 27. `The tension of the springs 3l may be adjustedby nuts ai.; Y* 1 The improved drawingyhead as illustrated Vand described may be substituted vlfor the drawing head Vnow in use upon finishing machines and in addition to the many ad- .vantages above mentioned, theconstruction of the head is suclitliat knots and bunches Vinl the fiber whicli'pass between the rolls will Y' product. ,Y
