Abstract
The invention relates to controlling the temperature in a tunnel (1) including heating or cooling means (4) disposed along its side walls and means (5) for blowing in a gaseous fluid at a given temperature along a direction essentially perpendicular to the direction which objects are conveyed along the tunnel. The temperature is detected in the zone of the tunnel into which the gaseous fluid is blown, and the blower means (5) are displaced in a direction essentially parallel to the direction in which the objects (3) are conveyed by means of a servo-control system for ensuring that the blower means move automatically when the sensed temperature differs from a predetermined temperature, thereby permanently providing a constant temperature environment for the, or each, object in said zone of the tunnel. The invention is particularly applicable to shrinking heat shrink sleeves onto flasks for decorative and/or protective purposes, and also to cooling down receptacles made of glass.
