Device for the drive of driving rollers of a calender for laminated glazings and calender equipped with this device
First Claim
1. A calender for pressing curved laminated glazings, comprising:
- a mobile frame;
pressing means mounted to said frame for pressing the curved laminated glazings, said pressing means including at least one series of pressing rollers mounted for vertical movement to follow the curvature of the laminated glazings, said at least one series of pressing rollers including at least one driven roller;
roller driving means including a rigid horizontal drive shaft mounted for rotation in said frame and connected to a driving motor for driving the drive shaft; and
transmission means for transmitting a rotation of said drive shaft to each said at least one driven roller, comprising at least one bevel gear unit slidably mounted to said drive shaft and a vertically extending, variable length jointed unit connected between each said at least one bevel gear unit and a corresponding said at least one driven roller.

Abstract
A device for the drive of driving rollers of a calendar for the pressing of laminated glazings 49 has at least one series of pressing rollers 1, 2 mounted on a mobile frame 3, at least one of these pressing rollers being driven by a driving motor 9 to which it is connected by a transmission system. Stationary and nondeformable drive shaft 11 is mounted on a mobile frame 3 and connected to driving motor 9 by a chain 10 or belt and to each driven roller 6 by the transmission system including a bevel gear 14 and a deformable, jointed unit 16 extending in an essentially vertical direction. The calendar equipped with this device can be used for the assembly of glazings of complex shapes.
