Abstract: A device for the elimination of trimmings of rolls or logs of ribbon-like material that can be connected below a cropper machine of at least one roll or log, in turn fed by a feed surface (11) of rolls (12) and top and/or tail crop ends (21), one after another, comprising, below of the feed surface (11), at least one conveyor element (16) closed in a ring which moves around a pulley (14) and which receives the rolls (12) and top and/or tail crop ends (21) on an upper section, the conveyor element (16) having an opening (17) with a dimension at least equivalent to the diameter of a log, inside which the top and/or tail crop ends (21) fall, the opening (17) being positioned as the conveyor element (16) rotates at the beginning of the upper section when the top and/or tail crop ends (21) reach this point.

Abstract: The invention described here concerns a unit for automatic container returns systems, with a conveyor device for transporting the containers in the direction of their longitudinal axis, with two rotary-driven rollers arranged along the conveyor path and which can be transferred from a neutral position into an identification position in which they release the container from the conveyor device and rotate said container, and with a sorting means for the selective, lateral removal of the container from the conveyor device according to the identification. It is the object of the invention to provide a generic unit for automatic container returns systems that is characterised by a simple construction.

Abstract: A device for the selection and elimination of crop ends of rolls of kitchen towel and/or toilet paper, in which the device is supplied by at least one row of finished rolls (12) and by top and tail crop ends (13) cut in sequence from at least one log, and including a structure (14) supporting an upper belt unit (16) and a lower belt unit (15a, 15b), facing each other to receive the rolls (12) and crop ends (13), the lower belt unit (15a, 15b) having a first, belt subunit (15a) and a second belt subunit (15b) separated by an opening (26), upstream the first belt subunit (15a) with a fixed lower surface (32) underneath the upper belt unit (16) to turnover the crop ends (13) and with a contact means (33, 35) being provided a the entrance of opening (26), on the turned crop ends to rotate them into the opening (26), letting the cut and finished rolls (12) pass by.

Abstract: A grading apparatus, especially for delicate material such as fish. The apparatus consists of a feeding device, ridged belts, rail guides for the transport and grading of material, grading compartments, a driving device and adjustment mechanism. The material to be graded is fed to the feeding device and therefrom onto the ridged belts, which transport it and grade it by thickness into the appropriate grading compartments. The apparatus is unique in that the feed device (4) consists of one or more interconnected and adjustable stages (4a, 4b, 4c). Each stage is equipped with side panels (67) or/and turning pins (55), side panels (67) dividing each stage into one or more channels (70) through which the objects are transported to thereby control the flow direction (77) and the velocity of the objects at each stage and onto the ridged belts (3).

Abstract: The machine for the sorting by size of pear-shaped objects comprises a conveyor (10) able to move essentially horizontally and comprising a first alignment of equidistant and parallel primary rollers (30) separated each from the next by an interval allowing one object to pass through. The conveyor (10) also has a second alignment of secondary rollers (44) each arranged in alignment with an interval. The machine has means (42) to guide the secondary rollers (44) along a sorting path (14) of the conveyor, the guide means (42) being such as to move the secondary rollers progressively away from the primary rollers along the length of the sorting path (14). The primary and secondary rollers do not rotate about their axis for the greater part of the said sorting path (14).

Abstract: The invention relates to a method and equipment for grading by thickness sensitive objects (particularly fish), large and small, involving gentle treatment of the objects, using ridge belts which are drawn by a drive along guides which are wider at the output end than at the intake end and covey the material gently without vibration or rubbing, together with infeed equipment.

Abstract: Apparatus for sorting articles according to size comprising an endless conveyor (13) including a plurality of elongate conveyor members (16) pivotally linked to a pair of continuous chains (22) by rigid rods (24) located at each end of members (16). Chains (22) are driven by sprocket (21) in a circuitous path defined by rigid tracks (60) and (63), idler sprocket (23) and catenary (76). Conveyor members (16) move in a substantially oval path (15) having a flattened upper portion (17) defining an article support surface (18), and a flattened lower portion (67). Members (16) within support surface (18) are spaced from one another by variable amounts by virtue of the circuitous path followed by chains (22), and the spacings permit selected size articles to pass therethrough and be sorted from articles of different sizes.

Abstract: An apparatus for advancing and sorting objects in respect of their size comprises a plurality of juxtaposed, endless conveyor belts (10) and gaps (9) between adjacent conveyor belts, each conveyor belt consisting of a plurality of hinged segments or chain elements (11) and a system (23, 24) for driving the conveyor belts. To obtain an advancement of the objects which is as lenient and noiseless as possible, the conveyor belts (10) are combined with and guided by guide rails (30) which extend substantially along the entire run of the belt which advances the objects. The guide rails are so arranged and designed, that the gap (9) between mutually adjacent conveyor belts continually increases along at least the major part of said belt run.
