Rollaweigh Options
The Rollaweigh can be installed in a number of formats. In some cases it is installed as a stand alone unit that can be fitted between feed sections. This is the basic unit. Quite often it is possible to split the feed section.
Depending on the configuration of the machine that will be fitted with a Rollaweigh, a choice of options may apply.
Dont worry about the specification, we'll do that for you. But here's some information on what the options are.
What's a dead zone?
A dead zone is an area of feedsheet before and after the Rollaweigh. The feedsheet is "dead" because it does not weigh or control fibre. It merely operates in synchronisation with the Rollaweigh.
A Dead Zone is necessary to stabilise the fibre so that it can be weighed with high precision. The dead zone before the Rollaweigh ensures that there is no influence from the volumetric chute. The dead zone after the Rollaweigh ensures that there is no influence from the action of the feed rolls.
Often it is possible to utilise the existing feedsheet to create the dead zones whilst in some cases, depending on the design of the card, a new section is built. Hence the Options.
Option 1
"Dead Zone" Conveyor before the Rollaweigh. Used in installations where the Rollaweigh has been fitted up to a feed sheet to deliver the fibre from the Rollaweigh to the feed rollers, normally used when the feed sheet is part of the feed section of the card.
Option 2
"Dead Zone" conveyor after the Rollaweigh. Used in installations where the Rollaweigh has been installed after the feed sheet, normally when the feed sheet is attached to the hopper feeder.
Option 1 & 2 can be used together to replace the feed sheet altogether, or for new card installations.
Option 3
Feed Roller Drives
Rollaweigh automatically controls the speed of the card intake rolls. Where a suitable high-resolution drive exists no replacement is required. In some cases the feed roller drive must be upgraded.
Option 4
Automatic Level Control in the Volumetric Chute.
Automatic control of the spiked lattice in the feed hopper produces a consistent feed batt whilst optimising the degree of fibre opening given by the beater. An automatic system is energy efficient ensuring that the lattice runs at the optimum speed and time, reducing frequent stop-starts and generally being kinder to the mechanical components and lattice.
