Arrangement for introducing banderoles or strips into receptacles

An improved arrangement for introducing banderoles into receptacles wherein the banderoles 16 are fed into guide passages 1 in which suction mandrels 2 are disposed for looping the banderoles 16, each guide passage 1 having an inlet slit 3 through which the banderole 16 is cut and introduced by the action of a pair of feed rollers 5 and a transverse cutting knife 6, the looped banderole 16 being thereafter transferred to a mold 7 by the mandrel 2,

• the improvement comprising,
• the guide passages 1 are disposed in a plurality of members which are disposed along two parallel lines 11, 12 and are fed with cut banderoles 16 from the same side;
• the knives 6 are also disposed along two parallel lines 13, 14 in staggered relationship;
• the distance between the cutting edge of a knife 6 and the inlet generatrix of a guide passage 1 is slightly less than the length of a cut banderole 16;
• and
• the suction mandrel 2 having two suction zones, the first zone 17 outletting into that portion of the suction mandrel 2 which confronts the front end of the banderole 16 which is introduced into the guide passage 1 at the moment the banderole 16 is cut by the knife 6, and which is coupled to a source of vacuum during the rotating of the mandrel 2 subsequent to the actuation of the knife 6 until complete looping of the banderole, as well as during the transfer to the mold 7, the second zone 18 outletting into that portion of the suction mandrel 2 which confronts the rear end of the cut banderole 16 at the end of looping thereof by the rotating mandrel 2, which second zone 18 is coupled to the source of vacuum only at the end of rotation of the mandrel 2 and during transfer of the banderole 16 to the mold 7.
