Abstract: In order to design a device for the destruction of a tooth free from transverse forces and bending moments comprising a destruction bolt which can be introduced into a bore of the tooth such that a destruction of the tooth is possible without transverse forces and bending moments being exerted on the patient it is suggested that the outer dimensions of the destruction bolt be increasable in such a manner that the tooth is broken and thereby split open by means of internal pressure due to application of symmetric forces in the bore.

Abstract: Starting from an apparatus according to German Offenlegungsschrift No. 3,123,496, an apparatus for wrapping relatively large articles, especially a plurality of individual packs (cigarette cartons), is simplified and improved in terms of its mode of operation, in such a way that the packs (20) formed in different ways always leave the apparatus at the same point (discharge conveyor track 40) and can be supplied to a common pack tower (41). For this purpose, there are two folding turrets (38, 39) for wrapping the pack group (22) with different blanks.

Abstract: In the production of cigarette packs, especially as hinge-lid or flip top packs, the introduction of a group of cigarettes, in the form of a cigarette block, into the partially folded pack is accomplished by feeding the cigarette block in the radial direction to a folding turret for the pack, the cigarette block being received in a block pocket during a transport stage. To prevent relative displacements in this stage, the cigarette block is fixed, during transport in the block pocket, by clamping.
