Special Surface Processing of Rubber Roller                                             (1) Slotting and spiral processingVarious cutting processes are carried out on the surface of COTS to make them more widely used. The main purpose of these processes is:Increase the amount of coating(2) Stretch the wrinkles of paper and film(3) Preventing slippage and snaking of conveyor belts(4) Forming of plastics, etc.Helping rubber roll to heat upGive rubber rollers flexibilityIncreasing friction coefficient_Improve the suitability of film and paperVarious cutting processes are shown in the figure. NameSection Diagram (Slot Shape)Suitable for groove patternSquare groove Vertical, transverse, helical, double helical, helical teeth, square, thread cuttingTrapezoidal groove Longitudinal, Transverse, Block, Thread CuttingV-groove Thread cuttingW serrated groove Semicircular groove Longitudinal and Thread CuttingCircular groove Vertical, horizontal and spiral cutting　　　　　　　D…depth R…radius FMountain spacing… W…Slot width P…pitchNamePlane plan (groove)Purpose and useLongitudinal groove Single longitudinal grooveUsage :Corrugated carton (paper roller)(Order instruction) Number of slots requiredTransverse groove (Single longitudinal groove)Usage: Corrugated carton (paper roller)(Order instruction) Number of slots requiredSpiral groove Spiral grooves with multiple spiral groovesUsage: Triple plywood, steel plate, etc.Roller for abrasive belt polishing machine(Order instruction)Need Cao NumberSpiral Angle Multiple Spiral GroovesUsage: Triple plywood, steel plate, etc.Roller for abrasive belt polishing machine(Order instruction)Need Cao NumberHelical angleDouble spiral grooves (multiple spiral central distribution slots)Usage: Triple plywood, steel plate, etc.Roller for abrasive belt polishing machineRollers for various thin films(Order instruction)Need Cao ShuyaoHelical angleSpiral toothed groove (One and more spiral grooves)Usage: Paper making, dyeing, etc.Spiral Tooth RollerVarious guide rollers(Order instruction)Need Cao NumberHelical angleReticulated groove (Reciprocating multiple spiral lines)Usage: Corrugated cartons, cloth, etc.Feeding rollRubber Rollers for Various Films(Order instruction)Need Cao NumberHelical angleThread Cutting Groove (Continuous threaded cutting slot)Objective: Usage: Triple plywood, steel plateCoating rolls for papermaking, etc.(Order instruction)About the size of the mountain(Left or right)
