Abstract
The invention proposes a chain for a machine drive, transport of material in a machine or the like, and also a packaging machine comprising one such chain, this chain being better than known link chains at meeting requirements in respect of hygiene conditions during operation and cleaning. This is achieved according to the invention in that flexible chain links (4) are provided between rigid chain links (2), the flexible chain links (4) being fixed to the rigid chain links (2).
Claims20
A packaging machine having a chain for driving a machine component or for transport of material, wherein the chain has a series of successive rigid chain links, connected to one another in a movable manner, and flexible chain links provided between the rigid chain links, the flexible chain links being fixed to the rigid chain links.
A chain for use in a packaging machine or a drive pinion, the chain comprising:
- a plurality of rigid chain links;
- and
- a plurality of flexible chain links, each of the plurality of flexible chain links being fixed between a respective pair of adjacent rigid chain links, the flexible chain links being less rigid than the rigid chain links;
- and
- the chain comprising a continuous flexible metal strip, such that the rigid chain links and the flexible chain links are formed from the flexible metal strip.
A chain for use in a packaging machine or a drive pinion, the chain comprising:
- a plurality of rigid chain links;
- and
- a plurality of flexible chain links, each of the plurality of flexible chain links being fixed between a respective pair of adjacent rigid chain links;
- wherein at least some of the rigid chain links have a clamping unit connected thereto, each clamping unit having lips for clamping packaging film.
