Abstract: An enhanced plastic net bag is provided and is configured to be used for the commercialization of food products. The bag has a longitudinal axis and at least one end. The bag includes a tubular mesh body fabricated at least partially of plastic material; and at least one laminar strip having at least one end. A closure is formed by an enveloping association between the at least one end of the tubular mesh body and the at least one end of the laminar strip by laying the laminar strip over the tubular mesh body and folding both the laminar strip and the tubular mesh body. The laminar strip is heat sealed to the tubular mesh body to form at least one heat weld wherein the at least one heat weld is transverse to the longitudinal axis. The at least one heat weld comprises a fused mass comprising at least two layers of the laminar strip and at least two layers of the tubular mesh body.

Abstract: Automatic scale for bulk products with a feeder mechanism composed of two sets of turning transverse eccentric rollers, with both sets having parallel eccentrics, which are smooth in one set and notched in the other set. The transfer mechanisms have pairs of discs with parallel transverse shafts, with the outside ones having a pin meshed in a fixed toothed wheel, while the central shafts are mounted ungeared. The linear transport mechanisms have rods for supporting the containers with pairs of sliding mechanisms, which are separated by elastic mechanisms and have control mechanisms for varying their distance apart. The weigh station has pairs of parallel, longitudinal endless belts.

Abstract: A bag-packaging machine has four pincers with a vertical flange and two oblique flaps which define an octagonal shape. The distance of these elements with regard to a central axis of this octagonal shape is governed, simultaneously and in synchronization, by regulator. A folding chute its provided. The chute is pivotable about a longitudinal lateral axis and is centered with respect to the axis of the octagonal shape. A securing and elevation device is provided for the upper part of a bag, a cutting and securing device is provided to separate the bags and a gathering device is provided for the bags.

Abstract: A process for obtaining packets full of products by means of a continuous tube of net, which comprises placing the net about a tubular means, pulling the top end of the net upwards and carrying it up to a certain height above the tubular means, expanding the portion of conveyed net sideways, pinching and closing the lower end of the net portion and shearing such portion, detaching it from the rest of the tubular net, filling the formed container and closing its top mouth.

Abstract: A machine for filling reticulate sacks having closing and holding bands, or the like, has a turning support with four crossed arms. Each arm having two vertical blades. Four stations are located about the support. A first station carries the sacks to the blades. A second station forms a loop and delivers the sack to a suspension device. A third station fills the sack. A fourth station closes the mouth of the sack and fixes such. The machine further includes an initial sack holding device, a loop forming device, a suspension device for each sack arranged at the four arms of the turning support, a hopper unloading the products into the sack and a vertically displaceable platform. A fixing device for the closure of the sack and a device for unleashing the loop on the band from the suspension device are also provided.

Abstract: Improvements in automatic weighing machines for food products that exhibit several buckets (6), arranged in a circle and in an overhanging manner, joined radially to a revolving central support (7) in relation to a vertical axis; each bucket is joined to the support by two horizontal, parallel and superimposed elastic bands (12), that allow for its vertical swinging; and these buckets pass successively over a station (13) with a single device for weighing (14) connected with the programming processing unit, and they have at least one of their walls (15) that is movable for the selective unloading of each batch of units of the product contained in the corresponding buckets selected according to the total weight desired, and this unloading is effected onto device (32)-(33) for conveying these batches toward the exit of the machine.

Abstract: An automatic labeling machine, for containers in the form of mesh bags or the like, includes a carriage 18 displaceable back and forth in a support plate 19, which incorporates a central, lengthwise channel 20, two lateral connecting rods 23 and 24 being articulated in the carriage, one with an external stud and the other with a lever 25, joined together at their free ends by means of a brace 26, in which is fixed a finger 27 carrying small catches 28, which can be introduced into the channel 20 with intercalation of the corresponding part of the label to be dragged toward the discharge from the machine; A push rod 32 temporarily retains the stud, provided with a plane 32a inclined to the inside in its free end and which can be freed by a bumper 36 joined to the corresponding connecting rod 24, and the lever 25 actuates a cutting device 16.

Abstract: A method for automatically filling a plurality of containers with products arranged therein in rows in one layer or a plurality of superposed layers in a pre-programmed geometric pattern. Empty containers are delivered in N rows to a container-filling station. The products to be contained in respective containers are automatically delivered one-by-one to supports equidistant from a vertical axis at the station. A vacuum suction is applied to the products on supports and they are raised above a level of the containers and held raised in fixed relative positions. While raised the products are rotated jointly about a vertical axis. Simultaneously during successive raisings of the products the containers are automatically positioned incrementally in a longitudinal direction and transversely thereof preparatory for lowering of the products vertically into the containers after each raising thereof.

Abstract: Machine for filling containers with products, in a predetermined distribution includes simultaneous feed means, with as many vibratory ducts transporting respective rows of products and with corresponding unit supports thereof; at least one rotating frame with vertical pneumatic cylinders and with as many lower suction cups at their pistons, communicating with sources of vacuum; a carriage with alternating transverse displacement, with means of longitudinal advance for at least one pair of containers and with transverse barrier and constraint means for the products, both coordinated; and a process programming unit.

Abstract: A trough has side walls tiltable around a shaft, which is horizontal and disposed radially relative to a rotational axis for a plurality of troughs arranged in a circle. The shaft is supported as a cantilever. Linkage mechanisms connect the tiltable side walls to a vertically displaceable member. When the displaceable member moves upwardly, the side walls swing outwardly to discharge the contents of the trough. When the displaceable member moves to its lower position, the side walls come together to close off the bottom of the trough. When the trough is closed, the linkage mechanism is in an overcenter locked condition, whereby the weight of produce in the trough resting on the side walls cannot displace the side walls to the open position.
