Abstract: A food processing apparatus for detecting and cutting tough tissues from food items such as fish, meat, or poultry. At least one x-ray machine associated to a first conveyor for imaging incoming food items on the first conveyor based on a generated x-ray image indicating the location of the tough tissues in the food items. A vision system supplies second image data of the food items subsequent to the imaging by the x-ray machine. The second image data including position related data indicating the position of the food items on the second conveyor prior to the cutting. A mapping mechanism determines an estimated coordinate position of the food items on the second conveyor by utilizing the x-ray image and tracking position data. The processor compares the estimated coordinate position of the food items to the actual position on the second conveyor based on the second image data.
Abstract: A modular oscillating head, particularly for stretching and softening industrial hides and similar products, comprising flexible mats (31, 32) for the continuous longitudinal advancement of the hides between at least one pair of plates with facing tools upon which actuation means act for producing their relative oscillation along a working plane (n) substantially perpendicular to that of the advancement. Two moving plates (7, 8) are provided anchored to respective beating bodies (3, 4) positioned on opposite sides with respect to a fixed supporting structure (2) along the working plane (.pi.). The beating bodies (3, 4) are provided with a symmetrical oscillating movement with respect to the central structure in the working plane (.pi.).
Abstract: An apparatus for tentering a hide including endless tentering mats (1, 2) driven along continuous upper and lower paths. The mats (1, 2) are pressed together over a portion of the continuous path by compressed air. A stretching assembly that grips the mat edges is used to continuously stretch the portions of the mats that are pressed together as they advance. An endless wire (5) is used to feed hides into the nip between the mats (1, 2).
Abstract: A skin holding device on an apparatus for letting out skins is driven by drive devices to follow the treatment and feed tools acting on the skin, so that the skin zone received in the skin holding device is moved synchronously with the skin zone gripped by the treatment and feed tools. In this way a skin, when being let out, can neither be distorted nor can it deviate from its initial angular alignment.
Abstract: An apparatus for letting out skins comprises behind the parting sword a needle bar movable up and down which is movable in addition parallel to the drawoff direction of the skin through a drive mechanism. Together with a supporting plate movable up and down, the needle bar acts on the skin section already let out so that it is held taut and flat.
Abstract: In flow presses for the production and processing of leather, especially in sammying (drying) machines, the need exists for a preliminary effective stretching and widening of the leather to prevent the forming of creases. In a flow press with a pair of pressing rolls (W1, W2), there is arranged for this purpose in the zone of the entrance wedge (EZ) of the rolls, a stretching device (ARV) acting transverse to the flow direction (P1) of the leather, which is adjustable between an open position (OST) permitting introduction of the leather, and a working position (AST) with stretching tools (RW1, RW2) acting on the leather. This permits a perfect introduction of the leather, with visual control and with possibilities of correction. The slight distance attainable between the end section (EA) of the stretching tool and the roll pressing zone (PRZ), especially with non-rotating plate-form stretching tools, favors the suppression of creases in the pressing process.
Abstract: Platform for introducing sheet materials, particularly in leather splitting machines and the like, consisting of a plate suitable to slide in a reciprocating manner on a fixed level disposed at the top of a bearing structure. Balls are interposed between said plate and the fixed level for the purpose of assisting the sliding of the plate itself which is also provided with a guide block that engages into a rectilinear guide obtained on said fixed level, two rows of balls being interposed therebetween. In addition, said plate is provided with means causing the automatic return of the same to its starting position.
Abstract: Equipment for letting out hides, in which the hides are cut several times obliquely to their lateral edges, the hide parts are then laterally offset and then sewn together again. A gripping tool is provided and is movable crosswise and lengthwise to the cutting line. After the sewing operation, the gripping tool seizes the cut edge and pulls the hide crosswise to the cutting line by the desired distance between cuts. Thereafter it moves the hide parallel to the cutting line, to obtain a constant distance between the sewing machine and the respective seam start on the hide.
Abstract: The invention comprises a machine for the continuous processing of leather hides using a table board which is fed lengthways through at least one pair of processing tools lying parallel and opposite to each other. The leather hide to be processed is placed with its middle part around the front edge of a table board. The machine includes means for displacing with respect to the table board, the unprocessed middle strip of hide on the front edge of the table board, to permit it to be processed.
Abstract: This invention relates to apparatus for moistening and conditioning sheet materials for example leathers and similar materials. The apparatus comprises two endless moisture-absorbent conveyor belts which come together, in the operation of the apparatus, between a pair of opposed flat presser surfaces. The apparatus comprises means for moistening the conveyor belts and for heating at least one of the flat surfaces. The apparatus also comprises means for moving the flat surfaces apart to permit introduction of material carried between the conveyor belts into the region between the flat surfaces and together to press the material on the belt. By reason of this pressure an intensive heat transfer occurs from the flat surfaces to the conveyor belt whereby the water in the conveyor belt is evaporated and transferred into the leather. The apparatus further comprises drive means whereby the belts are moved to transport the leather or other sheet material only while the flat surfaces are spaced apart.
