CALENDERING.
Application led October 27, 1921. Serial No. 510,786.
To all whom t may concern.'
Be it known that I, CLEMENT A. Ross- BAQH, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain ne'w and useful Improvements in Calendering, of which the following is a specilication.
My invention relates to calendering and the principal object of my invention is to provide new and improved means for suplying stock to a calender. Inthe drawings accompanying this specilicatiom andl forming a, partthereofI. have shown, for purposes of illustration, one form which my invention may assume.
In these drawings: y
Figure 1 represents a general view of this illustrative embodiment, while y Figures 2 and 3 are respectively a plan view anda side elevation of the stock-cutting mechanism shown in Figure 1.
The device herein shown comprises a warming mill 11, a stock-cutting mechanismv 12, a conveyor 13, a distributor 14, and a calender 15. The warming mill 11 and the calender 15 may be o-f the type now commonly in use. f
The stock-cutting mechanism 12 comprises'a pair of knives 1,6 secured to a block 17 which in turn is slidably mounted,on aA shaft 18 which may be xed to the warming-mill frame. The block 17 is provided with a pin 19 adapted to ride in the groove 20 of a cam 21 which is pivoted at 22 yfto any suitable support and driven by means `of a chain 23 acting on a sprocket 24 and itself driven by a sprocket 25 secured vto a shaft 26 on which is mounted a bevel gear 27 which meshes with the bevel gearr 28 mounted on the end vof the warming-mill roll 29. It is apparent from the above description that rotation of the warming mill 29 will rotate the cam 21 to thus -move vthe knives 16 back and forth alono the roll 29, as shown inl dotted lines in l:igure 2, to
thereby cause the knives to out a continuous calender, means to spirally cut stock from,
to convey said stock to strip 30 from the roll.
The strip 30 now passes to the conveyor 13. This conveyor consists of an endless belt -31 adapted toi carry the strip 30, a cooperating endless belt 32 adapted to press Y the strip 30 into rm engagement Withthe said calender.'
belt 31, and a transversely moving belt 33 adapted to receive the strip from the belt 31 and to 'deliver it to the distributor 414.
The distributor 14 comprises a framework 34 carrying a plurality of pairs of rollers35 between which the strip 30 is adapted to pass. This frame 34 is pivotally mounted at its upper end 36 and is oscillated longitudinally of the calender rolls by means of an arm 37 eccentrically connected to a disk 38 driven by means of a belt 39 passing around a pulley 40 secured to the disk and a drum 41 secured to a calender-roll shaft. It will be understood from the above that the strip 30 passes down between the pairs of pulleys 35 onto the calender roll and is then uniformly distributed by means of the oscillation of the framework 34 and the pulleys 35.
It will be understood by those skilled in the art that the thickness of the coating on the roll of the warming mill is practically constant for any given setting of the mill and accordingly it will be understood that the cutting device 12 will cut from this roll a strip of practically constant cross section which will be fed by the conveyor 13 at practically constant speed and uniformly distributed over the rolls of the calender 15 by the distributor 14. In starting or at any time when the feed is not sufficiently rapid the relative rate of feed may be increased` by operating the warming mill 11, the cutting mechanism 12, and the conveyor 13 faster than the calender is operated while in closing down or in case too much stock is being fed the warming mill, the cutting mechanism, and the conveyor may be Slo-wed down or stopped or in some cases the knives 16 may ,be merely lifted from the mill roll and the conveyor 13 stopped.
I have described herein one embodiment which my invention may assume but this description is of course illustrative only and my invention is not limited thereto.
I claim: 1. In combination, a warming mill, a
said mill, and means 2. In combination a warming mill, a calender, cutting means movable across the face of the mi'll roll to cut the stock thereon into a continuous strip, and means to convey said'st0ek to said calender.
3. In eomblnatlon a Warming mlll, a
calender, means for conveying material from said Warming mill to said calender' and means for distributing said stock along the calender roll.
4. In combination a Warming mill, a
calender, means to out material on the mill, means for conveying the cut material from the Warming mill t0 the calender and means for distributing the material along the calender roll. v
In testimony whereof I have signed my name to the above specification.
