The arrangement comprises a rotatable drum (1, Fig 1) with sleeves (3) comprising rocking walls (15, Fig 2), each of which sleeve is adapted to receive up to three boxes. The sleeves are heated either each individually or by a common heating body. All three boxes are ejected simultaneously by an ejector (9, Fig 2) which in case of a contact with the boxes always starts from a zero speed. To achieve this, the ejector (9) comprises a bushing (8), a shank (7), a compression spring (10) and a clamp (11) connected with a spring loaded pin (12) engaging into grooves of a grooved disc (13 & Fig 3), the depth of the grooves corresponding to the number inserted into the sleeve. The figure shows a third box being loaded against the ejector with a further representation on the right of the grooved disc. <IMAGE> |
