A method and apparatus for sealingly closing a pack for liquids in which the top of the pack is provided with a hole into which is fitted a pouring device that includes a cup-like recess which defines a flange. The apparatus includes a pivot device that pivots about a main horizontal axis. The pivot device includes several mandrels onto which the pouring devices are to be individually mounted. The mandrels are rotatable about their respective longitudinal axes to allow a thread of adhesive to be applied to the flange of each pouring device so that the pouring device can be subsequently attached to the top of the pack by joining the flange of the pouring device to the collar of the hole in the pack.

An apparatus for adding a first granular material which is disposed in a first container to a second granular material is provided and includes a conveyor conduit connected to a conveyor means, and a feed conduit communicating with the conveyor conduit for the feed of the first granular material which is to be added. In order to be able more easily to mix substances in powder or granular form, wherein the mixing ratio is to be continuously adjustable, the invention provides that disposed below the outlet opening of the first container containing the granular material to be added is a gap which is formed between two rollers. A communicating passage is provided between the gap and the feed conduit to provide the first granular material. By varying the width of the gap, the amount of the first granular material added may be quantitatively controlled.

An apparatus is described for moulding a plastics component onto a length of flexible web material, particularly a paper tube coated with thermoplastic synthetic material, the apparatus comprising a complete injection unit (5), a nozzle (26), an injecting head portion (12), external mould portions (11,11') and a core (14) which can be moved relative to these. As a means of increasing the output of the apparatus given a continuous supply of the web material, the invention provides that the core (14) is arranged on the end of a mandrel (23) which carries the length of material (35) with it and which is part of a rotatable mandrel wheel driven in cadence about its drive shaft (3), with its mandrel (23) projecting radially in one plane, that the external mould portion (11, 11') has at least two mould portions (11, 11') which can be moved apart and together laterally of the mandrel (23) to free the circular path of the mandrel (23), and that the mould portions can be held together by bringing them into positive and frictional engagement with a movable head plate (12) at the nozzle side.
