Calibrator for extruded material

摘要

The calibrator for plate like extruded products, particularly a wall section composed of a plastic, comprises an upper portion, a lower portion connected to the upper portion and a gap for the extruded material formed between them, the upper and lower portions being pivotally connected on one side by a pivot member. To allow a rapid and easy closing and opening of this calibrator a pivoting member pivotally attached to these portions and positioned for locking of the upper with the lower portion is provided. Further in the calibrator a cooling means through which a cooling medium, for example water, flows is provided. For even more efficient cooling a snake like channel for the cooling medium running transverse to the extrusion direction is provided. Both the above features can be employed independently of each other or used jointly.
