Embodiment Construction

[0027] from figure 1As can be clearly seen in the figure, the drive means consists of a chain 1, a gear wheel 2 and a guide in another form in the form of a pinion rim 3 or in the form of a sliding surface (not shown). The chain supports a plurality of sealing jaws 4a-4e, which are used to clamp together packaging tubes (not shown) to form a package. exist figure 1 In , two sealing jaw systems are shown, and only the right sealing jaw system is marked with a reference number. The left sealing jaw system is a mirror image of the right sealing jaw system with respect to the contact line between the sealing jaw 4 a and the corresponding sealing jaw belonging to the left sealing jaw system.

[0028] In order to achieve a correct parallel alignment of the sealing jaws, each sealing jaw system is usually provided with at least two chains which run parallel along a circular path. Among these two chains, only the front chain in the paper plane is shown in the figure, the front ch...

Abstract

The present invention relates to an apparatus for driving one or more processing stations, comprising an endless path (1) which includes a plurality of links (1b) of a first predetermined length (B) and at least one pinion (2) which is disposed to engage with said links (1b) and drive said endless path (1), the path (1) being disposed to support said one or more processing stations at a number of predetermined positions along the extent of the path (1), characterised in that each section of the path (1) extending between said positions, comprises at least one link (1a) of a second length (A) deviating from the first length (B). The present inThe present invention relates to an apparatus for driving one or more processing stations, comprising an endless path (1) which includes a plurality of links (1b) of a first predetermined length (B) and at least one pinion (2) which is disposed to engage with said links (1b) and drive said endless path (1), the path (1) being disposed to support said one or more processing stations at a number of predetermined positions along the extent of the path (1), characterised in that each section of the path (1) extending between said positions, comprises at least one link (1a) of a second length (A) deviating from the first length (B). The present invention further relates to a chain of the above mentioned type.

Description

technical field [0001] The present invention relates to an apparatus for driving one or more processing stations, the apparatus comprising: an endless path comprising a plurality of chain links having a first predetermined length; and at least one gear for communicating with The links are engaged and drive the endless path configured to support the one or more processing stations at a plurality of predetermined positions along the length of the path. [0002] The invention also relates to a chain consisting of a plurality of links having a first predetermined length which are connected together so as to form a circular path. Background technique [0003] USPS 2741079 discloses a packaging machine system for continuously forming a tube from a planar sheet and continuously filling the resulting tube and subsequently sealing the tube transversely to form a tetrahedral box. This sealing is achieved by means of sealing jaws which clamp and fuse together the plastic layers contai...
