BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for transferring onto a feed web in a plurality of parallel rows of upwardly extending longitudinal cylindrical containers to a single row of a delivery web, wherein apparatus is provided between two longitudinal side guides, of which at least one side guide is designed to perform a movement relative to the movement path of the containers.

From United States Patent No. 3,707,216, an apparatus of the kind mentioned above is known. However, the movable side guide of the apparatus is designed as a guide rail adapted to be able to move back and forth between two mutually inclined guide surfaces so that the side guide, in addition to a reciprocating movement, is substantially brought in its own longitudinal direction. to cradle in a plane substantially parallel to the path of motion of the subjects advanced. In practice, however, it has been found that with such an apparatus there is a relatively frequent clamping of the blanks and thus a blockage of the tapered transition area, whereby the vessels can sometimes be deformed.

The invention has for its object to provide an apparatus which is constructed in substantially the same simple manner as the apparatus initially mentioned, but so improved that the disruptive clamping of the container blanks in the transition area will only rarely occur.

This object is achieved according to the invention by an apparatus of the kind set forth in the preamble of the main claim and peculiarly in that the movable lateral movement is arranged to be able to perform a reciprocating movement in its own longitudinal direction only and with a frequency of less than 100 movements per . minute.

By allowing at least one of the side guides to move 35 in a distinctive manner, it is achieved that the often fragile containers are not damaged as a result of the pressure of an inward swinging or inward sliding side guide, but merely caused to rotate about their own longitudinal axis by contact with a longitudinal direction 2 141062 reciprocating sideways.

In an embodiment according to the invention, where both side guides are arranged to be able to perform a reciprocating movement, the two side guides 5 can be arranged to move back and forth in counter phase with each other. This ensures that the containers are transported undamaged through the tapered area, as the opposite rotating containers at the two lateral guides will slide off against the containers in the middle.

In a preferred embodiment of the apparatus according to the invention, a plastic part is arranged on the side guides, which is arranged for sliding on a metal rail. This provides even more gentle contact between the container blanks and a significant and very desirable reduction in noise level.

The invention will now be explained in more detail with reference to the drawing, in which: 1 is a top view of a transition area terminating in a single row, and FIG. 2 is a coupling diagram used for movement of the side guides.

In the embodiment shown, a transition area 1 consists of five parallel, relatively narrow paths a-e, on which containers 2 are advanced in the direction indicated by arrows at an ever-increasing speed.

A plurality of containers to be transferred to one row are arranged on the transition area 1 and intended for further delivery on a delivery path 3. In the area between the paths 1 and 3, two lateral guides 4 and 5 are arranged in wedge form.

These side guides form the transition area mentioned above.

The side guides 4 and 5 are moved back and forth at an even speed by means of a double-acting pneumatic cylinder 6, which is provided with a piston 7, the piston rod 8 of which is connected via a bracket 9 to the relevant side guide. The cylinders 6 are supported on the frame not shown. The reciprocating movement of the pistons 7 is conventionally provided using a pneumatic pressure medium. To this end, there are two wires 10 and 11, a control valve 12 and two relays 13 and 14 for controlling the operating speed. By means of the 5 shown in FIG. 2, the two side guides 4 and 5 can be moved back and forth in counter phase with each other.

The duration of each movement can be controlled by the relays 13 or 14.

In the embodiment shown in FIG. 1, each side guide 4 and 5 is constructed of a rail to which is attached a plastic part which is slidably engaged with a metal support part 15 on the rail.

In any of the above embodiments *, the velocity of the side guide or the relative movement of the side guides will depend on the air pressure in the pipes 10 and 11 and on the set frequency, which is most often between flour * limbs 45 and 100 pistons. minute.
