Convert a Manual Dough Feed to an Auto Feed

Automatically feed dough to the production line and eliminate manual handling Accurate and consistent dough feeding of the forming system is a major factor in the performance of a snacks production line. The preferred method of transferring dough is to form a sheet. Snack dough types tend to lack any natural binding forces that allow accurate metering and transfer. Typically, snack dough types need pressure to form a sheet. A pair of sheeting rolls is the optimum method of creating dough pressure and hence a continuous sheet. The advantages of a continuous sheet over randomly discrete pieces...

Rotary Cutter Modification for Dual Operation

Two snack products can be produced on the same production line without the need to change cutter rollers. The use of separate cutting and docking rollers is very popular in rotary cutting applications. The cutter pressure can be trimmed independently of the docker pressure. Usually, when operating the rotary cutter with separate cutting and docking rollers two rubber anvil rollers are required. They sit below the cutter web and accept the reaction force imposed on the product by the cutter / docker rolls. In order to increase plant utilization, a second cutter can be located in the docker...

Sheeter Roll Fatigue Crack for Repair

Rollers can be repaired after a fatigue failure at the bearing journal Sheeting rolls are subject to massive loads and high strains. Also, as the rolls rotate they are subject to a cyclic fatigue mechanism. Eventually, given the right combination of load, speed and time the roll will fail not by overload but by fatigue. Typically, rolls have a shoulder on the journal to position a bearing. The majority of failures occur at this shoulder rather than the centre of the roll. This is the point of maximum stress. The failure starts as a surface crack. It migrates at a slow pace towards the centre...
