Sleeve roll belt with pre-tightened yarns
Sleeve roll technology is described for example in patent publications
EP3382094, EP3333314
and EP3333315. One possible composition for the sleeve roll belt body is
published with patent
number EP2367980. However, the body of the belt can comprise otherpolymers and materials
too. Structures of sleeve roll belt will be/are published with patentapplications EP20175590
and EP20175592.
The belt for a sleeve roll comprises an inner surface and an outersurface. The belt can form aclosed loop and comprise an elastic body, and a reinforcing structure.
The reinforcing structure
can be a support structure supporting the elastic body. The reinforcing
structure can comprisefirst yarns forming a first yarn layer. The reinforcing structure canfurther comprise second
yarns forming a second yarn layer. The second yarn layer can be theoutermost yarn layer closest
to the outer surface of the belt. The first yarns are arranged to afirst direction, and the second
yarns are arranged to a second direction. The second direction ispreferably perpendicular or
substantially perpendicular to the first direction. The second direction
can further be parallel orsubstantially parallel to a travel direction of the belt. Further, thefirst direction can be parallelor substantially parallel to an axis of rotation of the belt and thenumber of reinforcing yarn
layers can be from one to five. The first direction is from now oncalled machine direction andis marked to the Figure 1 with letters MD. Sleeve roll belt is also
marked to the Figure 1.

RDISCLOSURE
Figure 1. Sleeve roll and sleeve roll belt.
The present invention is related to the manufacturing method, where theyarns in MD direction
are pre-tightened. During the manufacturing the pre-tightened MD yarns
are arranged to theelastic body. The pre-tightened MD yarns can be arranged to the outersurface or substantiallyclose to the outer surface of the belt. The pre-tightened MD yarns canalso be arranged to any
depth of the sleeve roll belt measured from the outer surface.
Pre-tightening of the MD yarns can move the neutral axis closer to theouter surface comparedto the yarn arrangement without pre-tightening. The closer the neutral
axis is located to theouter surface, the smaller is the slipping effect between the belt andforming fabric when thebelt is bending on top of the curve element, see Figure 1. The smaller
is the slipping effectbetween the surfaces, the lower is the friction factor between belt andforming fabric. Due tosmaller friction factor between the surfaces, the wearing of the wireand belt can also be
reduced. Pre-tensioning of the MD wires can thus facilitate savings inenergy consumption.
