The machine provides a low cost answer to weighing small tonnages into sacks of between 10kg and 50kg. The machine readily fits to hopper outlets and will operate in semi-automatic form in spite of variations in the level of materials in the hopper.

The operator places a sack on the spout and opens the gate handle. Material flows into the sack and the catchgate closes automatically.

Any under-weighments can be trimmed by jogging the catchgate. The filled sack is removed, a new sack placed on the spout and the gate opened.

Whilst the initial filling is taking place, the operator passes the previously filled sack through a sewing machine or other sack closing devices so that both sack filling and sack closing take place at the same time, thus giving an output of two or three sacks per minute.

It normally takes about ten seconds to fill a sack and between six and ten seconds to change a sack.

Interchangeable sack holders are supplied when a wide variety of sack sizes are to be filled.

The sack holder illustrated is normally used for paper sacks and keeps the neck of the sacks completely closed whilst filling is taking place.

When handling free flowing materials such as various grains and so on, the machine can be fitted underneath a hopper of almost any capacity. The smallest permissible size of feed hopper, is one which will store the on-stream material which will accumulate whilst a sack is being changed and the machine is not operating. Non free-flowing  materials such as flour and so on should be stored in small hoppers above the machine and care must be taken to ensure that material will flow into the machine inlet which is 200mm x 180mm. When these non free-flowing materials are stored in large capacity hoppers, it is necessary for some type of hopper discharger to be fitted such as a screw or belt feeder.
