Process for applying by shrinkage a thermally shrinkable sleeve on an article to be coated and apparatus for this application

摘要

The invention relates to the application, by shrinking, of a heat- shrinkable sleeve over an article to be coated, in which the article conveyed in a tunnel furnace is equipped with heating means. According to a fundamental aspect of the invention, the article (1) provided with its sleeve (2) is gripped by gripping means (3) in order to be tilted into an essentially horizontal position, that is to say substantially parallel to the conveying direction: in this way, the shrinking is carried out in this position, progressively from the front to the rear and in a perfectly uniform manner. The gripping means (3) then alone provide the conveying of the article with its sleeve into the tunnel furnace (100). Application especially to the decoration of articles or to the protection of articles against tampering, the said articles being able to be of very diverse shapes. IMAGE
