Abstract
Improvements in devices for fixing the free end portion of a roll of material to said roll, in particular a roll of plastic bags made end to end, with the help of at least a portion of adhesive tape, such as a label, which extends transversely to the axis of the roll and on a part of its periphery, on either side of the free end portion of said roll, characterized in that they comprise two cylinders whose axes are parallel and substantially horizontal, arranged so as to be able to be governed by a motor reducer to rotate around its axis in the same direction and at the same speed, these cylinders being distanced from each other a distance such that the roll of material placed between these cylinders is maintained between the latter and is driven in rotation by these for the placement of the aforementioned label, one of the cylinders being mounted on the device so as to be fixed according to a direction transverse to its axis and in a direction parallel to the latter, while the other cylinder is mounted in the device so as to be fixed in a direction parallel to its axis and to be movable in a direction perpendicular to said axis, being means are provided in said device for separating the movable cylinder from the fixed cylinder to allow the release of the roll of material between the two cylinders when said label is placed, the device also comprising a referencing system of the free end portion of the roll of material fixed in the device near the fixed cylinder and constituted by a U-shaped part whose wings extend parallel to the cylinders and are directed towards the cylinders, one of the wings supporting a pressurized air nozzle whose end portion protrudes between wings of the u, while the other branch of the u supports a channeling that protrudes equally e the wings of the u, the tubing and the channeling being located in the extension of one another, so that the jet of air circulates from the branch pipe towards the ducting, the part of the referencing system being secured, the branch pipe and the ducting so that the free end portion of the roll can be inserted between the branches of the u when, the roll is driven in rotation by the cylinders and forming screen enters the pipe and pipeline cited to interrupt the jet of air under pressure that flows from the pipe towards the ducting, means being provided for governing, in the absence of pressurized air in the aforementioned ducting, an automatic device for distributing and placing labels, whose part that applies the labels is mounted above the cylinders so as to be able to be animated by an alternate rotation movement around an axis parallel to the axis of the cylinders in order to bring it closer to the roll to place the label on the latter and thus separate it when the label has been placed, the latter means being arranged and synchronized as well as the means that separate the movable cylinder from the fixed cylinder so that the label is placed so as to staple the free end portion of the roll and to release the roll of the cylinders when the label is fully placed.
