. Automatic produce-bagging machine that uses factory-roll polyethylene net tubing. Fruit, Packaging; Polyethylene; Agriculture. In Florida most citrus bagging in polyethyl- ene film bags is done by semiautomatic ma- chinery; some automatic machines are in use. In all semiautomatic bagging operations, pur- chased (premade) bags are used entirely. The representative semiautomatic equipment used in a large portion of the packinghouses counts the desired quantity of fruit into the bag upon actuation of a foot pedal or other control by the operator. The operator holds the bag in position to catch the fruit, then closes it by a tape or stapling device, and places it in a master carton (fig. 2). Similar semiautomatic equipment is used elsewhere for packaging such produce as apples, onions, and potatoes in polyethylene film bags. Generally, this equipment measures quantity by weight instead of count. Machine action or the operator pours the measured quan- tity from a pan or accumulating chamber into the bag after the machine feed has stopped at a preset weight. Bag closing practices are simi- lar to those employed in semiautomatic citrus bagging operations. Semiautomatic machines suitable for polyethylene film bags are also gen- erally usable for bagging fruit in polyethylene net bags. Automatic polyethylene film bagging ma- chines have been installed in several Florida packinghouses over approximately the past 3 years. Premade bags are used by all of them ex- cept for one make that uses specially prepared film, doubled, in a ribbon with perforations in heat-sealed strips between bags. The bagging machine heat-seals the top after filling except where twist-tie or Kwik-lok closing has been substituted. Bags separate along perforation lines in passing out of the machine onto the takeaway conveyor (fig. 3). Manual checking of bag weight is required in operating one make of these machines, a carrousel type (fig. 4). No fully automatic machines are available for handling polyet
