Apparatus and method for packaging particulate product in bags for deposit into cartons of predetermined cross section and height. Sheet material is formed about a filling tube. The sheet material is sealed and severed beneath the filling tube creating the top of one bag and the bottom of the next. Product is dropped through the filling tube into the formed sheet material which is vibrated. A sensor may be used to determine if product exceeds a predetermined height. After a predetermined amount of product has been dropped into the sheet material, the material is lowered, sealed and severd to form a filled bag.

Settling systems for bag-in-box machines

Apparatus for forming bags of predetermined length with a predetermined weight of product, the apparatus being provided with a vibrator for effecting vibration of a bag shaper and a sensor adjacent the bag shaper for determining when the product has subsided to a level less than the height of the bag so that jaws may be engaged to seal the top of the bag without being jammed by product.

Cyclically operable apparatus for forming and filing bags

Apparatus for packaging particulate product in bags for deposit into cartons of predetermined cross section and height.

Apparatus comprising an accumulator for temporarily storing articles being transferred by a conveyor from one operation to another in the event that there is blockage of the articles at the discharge end of the conveyor and for restoring the articles to the conveyor when the blockage is dispersed including sensors and control circuitry for on the one hand transferring the articles from the conveyor to the accumulator and on the other hand transferring the articles from the accumulator to the conveyor.
