Key Specifications/Special Features:
Rolls are made of chilled cast iron of vanadium and titanium alloy
Roll face is hard and anti-wear
For heating up or cool down, rolls are either circumferentially drilled or centrally bored so as to make temperature well proportioned on the roll surface
Machine is driven by DC motor with a wide range of speed adjustment Working linear speeds can be steplessly regulated within the fixed range for different applications
Rolls are equipped with lubrication failure alarm device, as well as nip display and speed display
Rolls can be arranged in L and I forms
Top roll has camber that can eliminate bending impact on the roll in working process
Thus, it is possible to make products with same thickness along axial direction
Transmission system adopts hard gear speed reducer, which has a compacted structure with higher transmission efficiency, lower noise and longer service life
Machine is equipped with emergency device
When an emergent accident occurs, calendar will be immediately stopped to open the roll space so as to protect the operator and equipment
Machine is chiefly applied to put rubber on fabric, canvas or other fabrics to rubberize fabrics or to make rubber sheets
