PlasticsRubber - Extrusion - General Type Definitions

Several machines in an extrusion lines (e.g. calenders) contain rolls and gaps between rolls.

The RollsType defines a container for several rolls inside of a component of an extrusion line. It is formally defined in Table 6.

9.2.1 Id

Id of the roll

9.2.2 Name

(Human readable) name of the roll

9.2.3 MasterRollId

Id ot the master roll. If a roll is the master roll then MasterRollId = Id.

9.2.4 Drive

Information about the drive of the roll. The DriveType is defined in OPC 40083.

9.2.5 Temperature

Temperature of the roll.

9.2.6 CrossAxisLeft, CrossAxisRight

Axis crossing of the roll on both sides (in the direction of the material flow). The MonitoredParameterType is defined in OPC 40083.

Unit: mm or inch

9.2.7 RollPeripheralDevices

A roll can be equipped with infrared heating systems and/or cleaning systems. Their representations are put into the container RollPeripheralDevices. The RollPeripheralDevicesType is formally defined in Table 8.
