Abstract

832,127. Wrapping-machines. PACKAGE MACHINERY CO. Jan. 23, 1958 [March 22, 1957], No. 2282/58. Class 94(1). A device for overlapping the edge portions of a wrapper partially folded round an article being carried on a conveyer, comprises a series of transverse bars, moving at a speed greater than and in the same direction as the article, which engage the wrapper edge portions so that the leading one thereof is initially held away from the article while the trailing one is folded down on to the article. The invention is described as applied to a wrapping machine of the kind set out in Specification 770,124. The device is sited beneath the gap between spaced plates 30, 60 below the machine conveyer 20. The bars 32 are carried in spaced groups on conveyer chains 34, 36, with a single bar 32g in each gap initially between the groups. The wrapper has its leading portion x folded on to the article bottom face and its trailing portion y extending behind the article. As the article moves over the gap between plates 30, 60, it is supported by the last bar 32f of a group and the portion x springs down into the gap. A bar 32g engages the article and the portion y drops into the gap behind it. As the bar 32g advances relative to the article it folds back the portion x and the leading bar 32a of the next group lays the portion y onto the article. Finally, as the article travels over the plate 60, the latter lays the portion x on to the article and the portion y. The downward movement of the portions x, y may be assisted by air blown through ducts 90, Fig. 2 at the forward end of the plate 60 and tubes 106 above the gap. A reciprocating suction arm 70 may grip the portion x to pull it downwards. Reference has been directed by the Comptroller to Specification. 770,124.
