This invention relates to web winding and more particularly to improvements in apparatus for winding slit film, paper and the like as it comes from a-slitting machine.
In the manufacture of narrow webs of nonfibrous peliicular material such as regenerated cellulose film and'of fibrous peilicular material such as paper, it is customary to carry a wide web of pelllcular material past aligned slitting knives of a slitting machine and to wind the resulting narrower widths of web material on a suitable mandrel to form a package.
A windup arrangement currently used commercially in the packaging of slit film is as follows; a keyed spacing sleeve is first slipped over the surface of, and keyed to a driven wind-up mandrel or shaft. Then a paper core is slipped on the mandrel next tothe spacer, followed by another keyed spaclng sleeve, a second core, another sleeve etc. When the mandrel has been filled with spacing sleeves and cores, a spring-pressed abutment applies end pressure to the assemblage ..-to regulate the pressure, and therefore the friction, between the ends of the paper cores and the sleeves. The sleeves, being keyed to the mandrel, turn at mandrel speed while only the friction 'makes the cores turn. which produces the wind-up tension. The chief drawback to this type of a wind-up is that as the weight of the slit roll increases, the component of torque produced by the friction between the mandrel and the.
core increases since the core rests directly on the mandrel. and a poor winding pattern is obtained. It has been determined that the Optimum winding pattern for slit rolls results when the winding is accomplished under substantially constant torque conditions. Substantially constant torque winding minimizes blush and distortion of the web or film at the of! gauge locations, prevents excessive buckling or starring" of the web or film next to the core, and when the roll is subjected to freezing temperatures and allowed to return to normal temperature it exhibits good resistance to telescoping. Moreover, where rolls of unequal width or weight (due to difference in diameter) are wound upon the same mandrel, it is very difllcult to wind the wider or heavier roll with satisfactory film tension without imposing too great a strain on the narrower film.
An object of this invention therefore is to provide a wind-up device for slitting machines wherein the turning force on the roll of slit web is of substantially constant torque at all times 3 Claims. (CI. 24:45)
Another object is to provide wind-up means for slitting machines which will give unifm'mly luspacersandpapercoreateachendofthecole on the conventional wind-up mandrel. The assembly is constructed to support the paper case out of contact with the mandrel at all than, the collar at each end of the core together with the ll core forming, in eiiect, a wind-up bobbin.
