- Multiflex chains
These chains use a unique pivot to connect the hinge pin with the chain link. In standard side-
flexing chains the pin and hinge have to deal with horizontal rotation, due to the sideflexing of the
chain in the curve, and with vertical rotation of the hinge, when moving over the sprocket. The pivot
uncouples these movements, as the hinge pin is only involved in the rotations because of the chain
links moving over the sprocket. The pivot can rotate inside the chain link, allowing sideflexing in a curve.
Due to the pivot, multiflex chains are ideally suitable for running through multiple curves.
- Armor Clad
The 1700 multiflex chains are also available with a hardened steel cover, the Armor Clad AC 1700 K.
Because of this cover the chain is very suitable to convey parts with a high temperature that could
damage a plastic chain surface. The steel cover gives the chain an excellent wear life, to make it
suitable for part handling in automotive and similar applications.
- Safety
The ZeroGap 1765 and 2565 multiflex chain have a patented top plate design. The chain surface always
stays closed when the chain is running through a curve or over a sprocket. Both chains are commonly
used in packaging and automotive industry. The 1710 K and 1713 K multiflex chains also offer
surfaces preventing people’s fingers to be trapped if larger products have to be conveyed.
- Case conveyor chains
These chains have a very robust design, making them ideally suited for tough applications, such
as case and crate handling. They are very open to deal with the often abrasive debris in these kinds
of applications. The conveyor design for these chains can be very simple, resulting in a very
economic solution for the sometimes very long distances empty or full crates and cases have to
be conveyed in a production line.
- Pin design
Both Multiflex and Case Conveyor chains have chain links characterized by two legs. The pins have
a special design to prevent opening up of these link legs. This results in a high allowable working load.
- Corner discs
For multiflex and some sideflexing slatband chains, corner discs can be used to reduce the friction in the curves, allowing
a multitude of curves within one conveyor. The use of corner discs is mainly found in conveyors with low-speed part
handling in dairy applications, automotive part handling, tobacco industry, etc.
The N880 drive corner disc with a toothed contour is used to drive the chain, integrating sprocket and curve function in
the corner disc. This means that no return section for the chain is needed, making the conveyor design more simple and
economic. In this kind of conveyor design however the amount of pitch elongation due to wear that can be absorbed is
limited. The disc is mounted on the drive shafts by means of a clamping device, for which standard machine components
can be used.
The carry disc is used in the upper part of the conveyor, contacting the chain in the normal position when it is conveying products. The return disc is used in the return part of the conveyor, contacting the chain when it is in the upside-down position.
The ball bearing types of corner discs are recommended for high- speed and high-load applications; ball bearings are not included. In all other applications corner discs with thermoplastic bushings can be used.
An open corner disc is mounted on the shaft which needs to run through the disc. A closed corner disc is mounted on top of the shaft. Some closed versions, such as 880BO, offer the ability to break out a diaphragm in the closing cap.
