REXNORD - MARBETT - MCC
Plastic MatTop
Chains
With a large variety of MatTop executions and materials Rexnord has got a conveying solution for virtually any application,
especially in combination with the huge TableTop chain progamme. The MCC brand has set a standard for modular conveyor
belts in beverage industry and now the cleanable designs and specific accessories make several Rexnord MatTop series very
suitable for food industry as well. Also in many other industries, such as container making, pharmaceutical and automotive,
lines are equipped with Rexnord MatTop chains.
MatTop chains offer a reliable drive concept, using Rexnord great experience in chain drive technology.
The design of both belt and sprocket make a perfect combination meeting high standards for tooth and belt engagement,
belt release from the sprocket and allowable elongation. Rexnord and MCC MatTop chains are also known for their clever pin
retention systems, which make them very easy to install and maintain.
MatTop Chains
The range of MatTop chains varies from ½-inch small pitch sideflexing executions to 2½-inch pitch straight
running heavy duty solutions. The different series are offered in many variations to suit any application:
Solid Top/Flat Top
A fully closed surface is used if products require maximum support, due to their vulnerability or unstability,
and if small particles, such as broken glass, bolts and nuts, bones or the product itself, could get stuck in
the surface of the belt, possibly damaging or jamming the product or the belt.
Perforated Top/Flush Grid
An open area surface is used to allow water- or airflow through the belt and to remove debris, making sure
the contact surface between the belt and the conveyed product stays clean. Pollution is washed out in a
regular cleaning program. The open area varies per belt type.
Raised Top/Raised Rib
If (unstable) products need to be conveyed onto or from a belt or chain, Raised Top belts and fingerplates
are suitable. The fingers of the transfer plate reach into and below the surface of the ribs of the belt.
Fingerplates are available with longer and shorter fingers; short fingers are normally used in case of a risk
of broken glass.
Vacuum Top
Vacuum conveyors are mainly used for can making or empty can handling in beverage plants. Small holes in a Solid Top belt enable to handle the empty cans
by means of a vacuum underneath the belt.
Rubber Top/SuperGrip
On inclined and declined conveyors packs or crates can be handled smoothly using surfaces with rubber, moulded on top of a specially prepared module using
either over-moulding or 2-component technology, ensuring 100% secure bonding. Rubber Top chains can be used up to an angle of 20 degrees, depending on
the pack style and material.
Low Backline Pressure (LBP)
Handling accumulated products (cardboard cases, shrink-wrapped packs, flat based crates, tires, etc.) LBP chains are the best choice. LBP1005 chains are
recommended for shrink-wrapped packages without solid (cardboard) base and small packages, while LBP7703 is the best choice for (cardboard) cases,
shrink-wrapped packs with a cardboard bottom and larger products. Both executions guarantee optimum product protection and low noise operation.
Sideflexing
This belt range offers a solution for almost any curved application.
Metric and imperial widths
Most belt series are available in either metric or imperial widths. Metric width has developed as the standard of the (European) beverage industry, following
the standard 85 mm pitch between different strands of slatband chains.
This enables a high level of standardization between TableTop and MatTop conveyor design. Imperial widths, mainly used in the North American market, are
the standard in many applications outside (European) beverage industry.
Positrack guiding system
In several MatTop series Rexnord offers Positrack or Tab guiding. This system consists of two lugs underneath the belt, offering an easy way to guide it in
the conveyor. Positrack has advantages if lateral forces apply, as on side transfers of beverage containers and products entering from the side otherwise.
The system retains the belt on the conveyor frame without the need for additional wearstrips at the sides.
The lugs are usually situated on one side only (double Positrack) allowing for belt expansion without
interfering with the accurate guiding of the belt.
Dynamic Transfer System (DTS/FreeFlow)
The DTS
option makes it possible to construct self-clearing 90-degree transfers on which no products are
left behind, avoiding the use of dead plates. A narrow DTS or FreeFlow belt is often used next to the main
conveyor belt. Due to the constant moving belt underneath the product, pressure between the products, and
therefore noise and product damage, is minimized in comparison with dead plate transfers. This system is
available on 1500, 8500, 1000, 1005 and 7700-series.
Flights and sideguards
In several series flights and sideguards can be selected. Due to the great variety in positioning of these
accessories these belts don’t have fixed codes.
On the product page a table is added explaining the possibilities; examples are given how to make a
description for the desired product configuration.
