Method and apparatus for foil-capping bottles
First Claim
1. In an apparatus for the foiling of bottles with a patch, having at least one point, comprising a turntable which has several controlled bottle turning means disposed at its periphery, at least one labeling station which transfers the foil patches to the bottles moved past it by the turntable and brought to a certain rotational position by the bottle turning means, elements for pressing down the foil patches transferred to the bottles, the elements being disposed along the transport path of the bottles, and a transfer wheel disposed after the turntable and provided with receiving places for the bottles, the transfer wheel having a clamping means for the bottles and means for turning and pressing down patch ends projecting above the tops of the bottles, the improvement which comprises clamping means holding the bottles against rotation on the entire transport by the transfer wheel, the turning and pressing means including a plurality of units disposed above the transfer wheel and turning with the transfer wheel, each unit being associated with one receiving place, means for pivoting each unit in coordination with the rotational movement of the transfer wheel from a first position laterally alongside the corresponding receiving place to a second position over the corresponding receiving place, means for lowering each unit in its second position axially against the top of a bottle held in the receiving place, a fold-down device, and a smoothing and pressing element disposed behind the fold down device in the direction of pivoting from the first position to the second position and, when lowered, gripping the bottle top on all sides.

Abstract
There is described an apparatus and a method for the foil-capping of bottles with a patch of metal foil having a point and an adhesive back, comprising
(a) adhering each patch to the neck of a bottle by its central area with the upper area of the foil projecting above the bottle neck,
(b) applying the laterally projecting patch ends so that they overlap one another,
(c) folding down the area of each patch projecting above the bottle neck to the bottle side away from the patch point, and
(d) simultaneously pressing down and smoothing the folded down patch area onto the top side and all about the circumferential margin adjacent thereto.
A neater tear-free arrangement of the foil about the top and sides of the neck of the bottle results.
