An apparatus for enclosing objects, for example, candies, with a sheet of packaging material has a tube forming and guiding apparatus. To tightly fit the tube to the objects, an elastic collar is arranged at the end of the tube forming and guiding apparatus in the shape of a funnel and under tension, so that the collar presses the tube against the objects and forces superfluous packaging material into an overlap of the packaging material edges.

A six-pack of bottles is provided by encircling mid portions of the bottles with a retainer and engaging a paper board carrier and retainer beneath the bottle caps. The paper board carrier has rows of apertures formed therein for receiving the upper ends of the bottles, and is assembled with the bottles by conveyor and guide means which advance the bottles and carrier continuously along a path of travel, initially fold sections of the carrier along lines intersecting the apertures for opening the apertures to receive the upper ends of the bottles and then reversely fold the portions of the carriers for closing the apertures and securing the carrier with respect to the bottles.

A pair of parallel conveyor belts 20, 21 are spaced apart less than the width of a web 11 of packaging material to be transported, but greater than the width of a package to be wrapped in blanks 10 severed from the web. Suction holes 24 in the inner edges of the belts hold the overlapping outer edges of the web. A transverse knife 27 slightly wider than the web passes through oblong cutouts 30, 31 in the inner edges of the belts to sever the blanks, which are subsequently U-wrapped around packages 13 individually pushed between the belts.

Method and apparatus for wrapping flat articles wherein each article with its wrapping material is pushed through a folding tunnel for the purpose of partially folding the wrapping material about the article, and each article is then transported to a final folding station; additional folding operations being performed during the transport. The next cycle of operations in the apparatus is begun during this transport.

A device to be mounted on a wrapping machine to fashion the wrap on candies or similar products in "single end" or "double end" twist styles of wrap. An axially sliding sleeve has a pair of twist fingers symmetricaly pivoted to one of its ends. A rod slides in an axial direction in the inside of the sleeve for opening and clising the fingers. Gear means are provided for causing the sleeve and the rod to rotate in unison, and for cooperation with a pair of gears for sliding the sleeve and rod. One of the gears of this pair is mounted rotatably and slidably on the rod; the other is mounted rotatably but non-slidingly on the sleeve. The gears of this pair have inclined web structures. In conjunction with fixed guide rollers they operate the rod so that it is given a reciprocating movement with respect to the sleeve.One gear in each pair is connected to the said gear means that cause the sleeve and the rod to rotate in unison, whilst the other, mounted in a rotatable but non-sliding way on the sleeve, rotates and slides in contrast with the aforementioned flexible means on the rod. The gears mentioned last, structured in their plane of rotation, are helical and behave like a front type cam, so as to operate, in conjunction with the fixed guide and support pressure means, the said rod so that it is given a flexible movement with respect to the sleeve and both the said sleeve and the said rod jointly with a reciprocating movement.On the said device the fingers of the twist finger assemblies are operated without the aid of cams and levers; thus the said device can be used in conjunction with very high unit output speed wrapping machines producing something in the region of a thousand and more wrapped products per minute.
