Apparatus for the production and deposition of bands

An apparatus for the production and deposition of bands associated with shaping moulds of a shaping station of an installation for the thermal shaping of containers provided with bands, whereby said apparatus comprises an elongated body at least one preferably cylindrical, so-called winding cavity, at least one fixed cutting member and one movable cutting member located in the immediate vicinity of said cavity, at least one access slot issuing into the said cavity and which connects the latter lateraly with the outside, at least one ejecting plunger mounted without any significant lateral clearance in the said cavity in such a way that it can occupy two end positions in the latter, actuating means for the movable cutting member, at least one pair of transporting rollers located upstream of the access slot, a strip whose width is at the most equal to the height of the slot whose free end is gripped between the said transporting rollers and from whcih the bands are cut, as well as driving means able to sequentially drive the two transporting rollers for the purpose of introducing into the said cavity a strip portion whose length is equal to that of one band, wherein each pre-winding cavity is located below a mould and the body containing the various cavities is integral with the block of moulds, each ejecting plunger is fixed in space on a frame, each mould comprises base plate aligned with the corresponding cavity integral with the ejecting plunger by means of an intermediate supporting member and whose cross-section is smaller than that of the shaping chamber of the mould in such a way that there is a marginal base portion between the side walls and the movable base plate of the mould, whereby the base plate, intermediate supporting member and ejecting plunger are arranged relative to one another and relative to the shaping chamber and the pre-winding cavity in such a way that the upper face of the movable base plate is located in the same plane as the marginal base portion and the intermediate member is located entirely within the said cavity when the ejecting plunger is located at the lower end of said cavity, the intermediate supporting member has a cross-section which is smaller than that of the ejecting plunger, each pair of transporting rollers is mounted so as to be fixed in space and extends parallel to the supporting member substantially over the entire height of the latter starting from the ejecting plunger, the actuating means for the movable cutting member comprise a control member which is independent of the movements of said movable cutting member and which are parallel to the axes of the mould and the cavity, and the driving means for each pair of transporting rollers comprises a reverse movement control which can be operated at the end of the cutting stroke of the movable cutting member and automatically stops the reverse movement of the transporting rollers as soon as the latter have moved back the end of the strip engaged in the slot to an area located outside the displacement path of the mould or moulds.
