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 packing machine for the packing of products in mesh bags with handle include; a tubular mesh feeder, a first set of rollers in quincunxes, a frame with a second set of rollers resting, respectively, on the first set of rollers, feeders of two bands, plates with springs disposed between both bands, parts shaping folds on the free parts of the mesh, rollers that pull the tubular mesh with its two bands welded, and means that close the bottom and cut the top of each bag, feeder rollers of a band and means for transversely cutting the band to obtain a strip, turning means that fold the strip in a “U”, and means for inserting the strip in the upper part of the bag and means for welding this set.

Abstract: A machine for manufacturing, filling, and closing bags of meshed fabric, from a continuous roll of meshed fabric of the type which manufactures inverted bags comprised of a portion of tubular meshed fabric closed at the top by a sheet folded over itself, which includes a first station for feeding the meshed fabric provided with first pressing members, second pressing members and cutting means; a second feeding station of the thermoweld sheet, which is to comprise the closure of the mouth of the bag, provided with a feeder device of the sheet; means of folding the sheet, means of welding the sheet; means for applying said sheet, and means of cutting the sheet; a third station for filling the bag in inverted position, provided with adjustable cams for separating the second pressing members, lower means of support for the bag, and means of filling the bag; and a fourth station for tying a belt string, closing the bottom of the bag, and unloading the filled and sealed bag, provided with a device for tying a belt

Abstract: An automatic product weighing machine, for food products having two buckets radially arranged in two concentric paths on a horizontal plane, with frames having an intermediate cross-member, each of which loosely houses a pair of buckets joined to the frame by pairs of flexible, resilient and parallel straps. Two radially aligned weighing apparatuses are respectively arranged below two buckets at the weighing area. Rollers at the free ends of the frames and on two sides of the buckets, stand on respective track sectors, and the buckets are lifted in the sector of the weighing area. Control metering of products to be delivered into buckets comprise of displaceable laminar belts.

Abstract: IMPROVEMENTS IN PACKING MACHINES OF PRODUCTS IN MESH BAGS WITH HANDLE that include: a tubular mesh feeder, a set of rollers in quincunxes, a frame with another set of rollers resting, respectively, on the former, feeders of two bands, plates with springs between both bands, parts shaping folds on the free parts of the mesh, rollers that pull the tubular mesh with its two bands welded and means that close the bottom and cut the top of each bag, feeder rollers of a band and means for transversally cutting it to obtain a strip, turning means that fold the strip in “U”, means for inserting the strip in the upper part of the bag and means for welding this set.

Abstract: Improvements in the object of the U.S. Pat. No. 5,294,283 for an automatic labelling machine for packers in bags of mesh or the like, which have: a second roller (101) with its counter roller (102), some independent means of activation (120), (121), and (123) of the means of cutting (16), of the cart (18), and of the finger (27) with claws (28); the printer head (10) and the counter roller (102) both being mounted on elastic laminar supports (112) and (104), with keying in their respective operating position; and mechanical linkage of turning (127) and (128) of the second roller (101) and of the roller (6).

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.
