Abstract: A method and apparatus is disclosed for conveying individual blanks, one at a time, from a stack of blanks in a magazine to a form chamber in an erecting machine. The magazine includes bottom and side guides and a conveyor for moving the blanks into a pickup position. A suction cup device is utilized to grip an upper portion of the blank in the pickup position and swing the blank into engagement with a bolster roller set. A segment device having a curved surface is also disclosed for coacting with the bolster roller for swinging the blank from a substantially vertical position to a substantially horizontal position for conveying into an erecting machine.

Abstract: A selection and setting apparatus in box or carton blank erecting machines which enables changing of the blank format in the machine. The apparatus includes format selectors coacting with at least two setting wheels. The setting wheels each include at least two pins which are of different lengths enabling settings for different formats. The free ends of these pins contact coacting stops arranged on the erecting tool or carton blank magazine in the machine which are movably settable to the blank size in question.

Abstract: An apparatus for automatically adjusting the dimensions of the carton blank magazine in a machine for forming carton blanks to select a variety of predetermined sized carton blank formats and for delivering the carton blanks to an exit of the machine. The apparatus includes a pair of movable side tool portions and a movable bottom tool portion for guiding a carton blank. A format selecting wheel corresponds to each of the tool portions and each format setting wheel includes a plurality of pins having a different length corresponding to one of the dimensions of a particular predetermined carton blank format. Each of the pins has a free end which engages a respective bottom or side tool portion to fix the portion in a position determined by the selected blank format. The apparatus further includes a bottom guide device for delivering the carton blank to the exit of the machine.

Abstract: A method and apparatus for sealing a filled, flanged carton tray with a flat lid. The tray is advanced into a sealing machine while resting on a conveyor (3) and at random spacing between trays. At a predetermined position the tray has a lid (2) placed on it, the lid (2) engaging against a stop curtain (4) and awaiting the tray (1), this being the lid (2) which is to be sealed against the flanges of the tray. The tray with the lid on it is then advanced by rollers (5-8) into a first microwave applicator (11), which includes longitudinal rails (12, 13) with a C-shaped cross section, for sealing a pair of opposing lid edge portions against respective flanges of the tray (1), subsequent to which, compression or sealing rollers (14-17) situated in the advancing direction of the conveyor press against the lid (2), which was sealed immediately previously, and before the tray (1) is turned 90.degree.

Abstract: The invention relates to a method and apparatus for packing products (2) coming from a product line using packing blanks in a packing machine including at least one conveyor for advancing the blanks (1) through the machine, as well as erecting means for erecting the blanks around the products during conveyance through the machine. In accordance with the invention, the blanks are advanced upstanding from a magazine in the machine with the lid directed upwards, simultaneously as products (2) are advanced with the same direction, speed, spacing and number as the advanced blanks.

Abstract: The present invention relates to an arrangement in a sealing machine through which there extends at least one conveyor (2,3,8,9), which has a plurality of constraining means (19) at predetermined spacing in the conveying direction for packages (7), which are intended to be sealed in the sealing machine after they have been filled. The conveying means comprises one or more belts (5,6,10,11) side by side and in the same plane and said constraining means comprises perforations (19) in the belts, the openings of the perforations facing towards the interior of the conveyor being in communication with a vacuum source and the openings facing towards the carrying surface of the conveyor being intended for coaction with the underside of the packages (7) placed on the conveying means and in that the packages (7) are located on the conveyor belt during conveying through the sealing machine with the aid of the suction achieved via the perforations (19) with the aid of the vacuum.

Abstract: The invention relates to a method and apparatus for rejecting too short and/or too low products, particularly so-called fish fingers. Products (7, 8, 9) are advanced on at least one conveyor (1) towards a final position or stop (11) at a reception unit (3). In the area of the free end portion (2) of the conveyor (1) there is a restraining member (6) displaceable in a vertical direction towards the product flow, the member (6) being adapted such that in a stepwise advancement of the products by the conveyor (1) it can arrest or clamp products (7) of the right length and height, whereas faulty products (8) are removed with the aid of a lowerable hatch (4). The conveyor (1), hatch (4) and the products on the conveyor are arranged for displacement a short distance opposite to the advancing direction at the rejection operation, the product or products in the final position on the reception unit (3) being no longer urged by the following products and are removed, e.g. for further conveying to a packaging station.

Abstract: The inventive tray includes a bottom (2) and four side walls (3-6), which have an extension in the form of a folded-out edge flange (11) in a plane parallel to the bottom (2) of the tray (1) and forming a continuous frame for coaction with a separate lid, sealable to the tray (1). At their upper portion (9) the side walls (3-6) are inclined inwards so that the continuous frame formed by the edge flange (11) is substantially within the outer contour of the side walls (3-6).

Abstract: In the erection of a tray having edge flaps with end flaps which are to be fastened together for forming a rim of edge flaps intended for receiving a lid, the erection is performed in two separate tools. In the first tool only the one pair of opposing edge flaps are folded out, whereafter their end flaps are folded up and attached to the outside of the second pair of end flaps. The partially erected tray is then ejected from the underside of the forming chamber and transferred to a second tool where all edge flaps are subjected to being folded downwards.

Abstract: The invention relates to a tray having two handle configurations along two opposing side walls, the configurations comprising extensions in the form of flaps extending obliquely outward and downward from the upper edge portion of the two side walls, the flaps being held in position by being secured to projections extending from the ends of the two other side walls.
