Abstract: The invention relates to an improved sealing head for sealing a cover made of a foil material onto a packaging container, in particular a plastic cup. The sealing operation is carried out by means of a heatable sealing head. This sealing head includes an insulating body which provides for the compensation of form and position deviation between the sealing head and the plastic cups which are to be sealed. This insulating body simultaneously provides for the thermal insulation between the sealing head, on the one hand, and the drive arrangement, on the other hand. Thereby a flaw-free sealing is achieved and any down-times due to malfunctioning of the arrangement are substantially reduced.

Abstract: The invention relates to a bending apparatus for wires having a cross section which varies according to their lengths, and comprising two cylindrical sections and an interleaved conical section. The wire is bent by means of three rollers. The bending roller is mounted on a carriage and determines the bending degree imparted to the fed wire. The wire is bent despite its variable diameter so that it is deposited with a regular curvature on the reception plate. To this effect, the curvature of the conical section is changed between the correct curvature of the thinner cylindrical section of the wire and that of the thicker cylindrical section of the wire. It only requires a simple switching at an appropriate time to obtain a sire bobbin which may be deposited on the reception plate. The appropriate switching time is situated between 20% and 60%, but preferably between 30% and 40%, and is calculated from the beginning of the wire diameter increase.
