Read Onforces by actually decreasing web tension as the roll builds. The amount of taper tension is normally measured in percentage of set tension. For example, using the same 3.5 inch core diameter and 35 inch outside roll diameter, if taper tension was set to 50%, the tension will be linearly decreased from 3.5 inch core to 35 inch roll diameter so the

Read OnI recently bought a taper-mike and find it very accurate on male tapers. I like gage balls for tapers. For location of a certain diameter on a male taper I'd use 2 gage pins held parallel a known distance apart and drop the taper between the pins, measure from the pins to a known feature on the shaft and do the trig.
Read OnThe solution to the shape control problem for a Sendzimir mill, utilising the As-U-Roll shape actuators, is well understood. The tapered first intermediate rolls, however, provide a …
Read OnThe BFI measuring rolls use piezoelectric pressure gauges which – spread over the width of the strip – are installed in bores under the roll surface. They measure the strip tension distribution as the strip passes over the shapemeter roll. Permanently reliable. The telemetric data transmission from the roll – without slip rings ...

Read OnThe rule of thumb for the maximum oscillation speed is 25 mm (1 in.)/min per 150 m/min (500 ft/min) of winding speed. Ideally the oscillation speed varies proportional to the winding speed. As a roll of flexible packaging film …
Read OnThe tolerance is the maximum allowable difference between the actual measurement result and the target at each station. Total crown is the difference between the reading in the middle of the roll and the average of the readings …
Read Onthe winding tension is tapered smoothly as the roll diameter increases. The tension taper should be between 0 and 50%. A tension taper of 25% at full roll is common. Tapered tension reduces 'end crowning', 'buckling', 'starring' and 'dishing' roll defects in rolls of flexible packaging film material. Strain Curves for Various ...

Read OnThe principle of increasing the contact force will increase the roll density (it will be harder). This is something that should be borne in mind when looking at alternative methods of winding. The fact that the roll density increases as the contact force increases is the basic principle of nip induced tension or wound in tension (WIT).
Read Onroll profiles of a temper rolling mill [53] and a variable crown rolling mill [ 54 ] were optimized, and roll-bending control efficiency and strip quality were improved.
Read OnST135 LineGAP. The ST135 LineGAP system quickly and accurately measures the gapbetween rolls in thin-slab caster segments. For best quality casting and smooth operation of the machine, it is essential to keep pass line geometry and operation conditions as designed. Improper roll gaps can often lead to product defects and increased mechanical wear.
Read OnConsistent grinding and balancing of rolls is necessary for efficient operation and optimum paper quality. As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving.
Read OnKaiser rolls are great for picnics, sandwiches, and other summertime meals. The hardest part about making them is shaping them. If you want them to be perfect, order yourself a kaiser roll stamp. Or you can roll out the dough out and knot it the way Peter Reinhart suggests in The Bread Baker's Apprentice. Below I'll show you the technique I've found easiest.
