Abstract: An arrangement for controlling longitudinal forces acting on a web of packaging material being wound from a first reel to a second reel, said arrangement comprising a first roller having a first rotational axis and a second roller having a second rotational axis, wherein the first rotational axis is fixed while the second rotational axis is movable.

Abstract: Device and method for controlling axial forces acting upon a moving web comprises first, second and third rotatable rollers. The third roller is between the first and second rollers and is movable in a circular path in the vertical plane between lower and upper positions in response to axial forces acting at any moment upon the web. To enable a simple manual installation of the web, the upper position of the third roller is at a sufficient vertical distance above the first and second rollers to form an open horizontal passage through which the web can pass freely between the first and second rollers and the above-situated third roller. Axial forces are controlled by biasing the third roller with a force which counters the motion of the third roller in the direction of the upper working position and which is less than the ultimate tensile strength of the web.

Abstract: The disclosure relates to an apparatus for flexographic printing of a web of packaging material. The apparatus has an anilox roll which is rotary in an ink pan or chamber for picking up and transferring printing ink to an impression cylinder which is rotary adjacent the anilox roll and forms, together with a counter pressure cylinder rotary adjacent the impression cylinder, a nip through which the web is led for receiving printing ink from the impression cylinder. In order to prevent printing ink from drying and adhering to the anilox roll, the apparatus displays a spray- or shower device through which a cleaning fluid for the printing ink is applied on the circumferential surface of the anilox roll.

Abstract: A method in the manufacture of a web-shaped packaging laminate (22) comprising a core layer (24) of paper or paperboard, the method including the steps of coating (38) a first side of a material web (40) of paper or paperboard with an outer layer (26) of thermoplastic material, an thereafter forming, with the aid of laser burning (46, 48) on the thus thermo-plastic coated first side of the packaging laminate (22), a perforation line (32) through said thermoplastic layer (26) and said core layer (24). After said coating (38) with the thermoplastic material but before the formation of the perforation line, the packaging laminate (22) is compressed (44, 10) on said first side for the formation of a compression line (30) in which said core layer (24) is compressed, whereafter said perforation line (32) is formed in said compression line (30). The present invention also relates to a plant in the manufacture of the packaging laminate, as well as the thus produced packaging laminate (22).

Abstract: The present invention relates to a system and a method for microlithographic writing and inspection on photosensitive substrates, and specially printing and inspection of patterns with extremely high precision, such as photomasks for semiconductor device patterns, display panels, integrated optical, devices and electronic interconnect structures. More specifically the invention relates to compensation of substrate offset by modifying the position data or the feeding of the same of the deflector, and the use of a direct digital synthesis (DDS) unit for generation of the sweep frequency drive signal.

Abstract: The disclosure relates to an apparatus in an adjustable creasing tool (1). The creasing tool (1) includes two mutually co-operating creasing rollers, a male roller (2) and a female roller (3), a gear wheel transmission with a housing (8) for operation and mutual co-ordination of the creasing rollers (2, 3), means for adjusting the mutual position of rotation of the two creasing rollers (2, 3), means for adjusting the position of one of the creasing rollers along its axis of rotation, and means for adjusting the mutual spacing between the axes of rotation (4, 5) of the creasing rollers.

These permit adjustment of the mutual positioning of the rollers (2, 3) without the meshing relationship of the transmission (8) needing to be affected.

Abstract: Variations in received signal amplitude caused by filter characteristics are reduced by a C/I measuring apparatus for a signal having a fluctuating carrier-frequency, comprising a filter for filtering the signal and means for splitting the signal into an RSS signal representing the signal strength and a BB signal representing the momentary carrier frequency deviation, comprising means for measuring the RSS signal unaffected by the frequency dependent attenuation in the IF filter. A method of measuring the C/I of a received signal is also disclosed. The method comprises the steps of filtering the signal using an IF filter to obtain one signal channel, feeding the signal to the FM detector and the RSSI unit, and measuring the signal strength of the received signal at a selected, substantially constant, carrier frequency.

Abstract: The disclosure relates to a safety device in an opening arrangement for packaging containers, the opening arrangement having a part fixedly connected to the packaging container and a lid portion displaceable in relation thereto. In the closed position of the opening arrangement, a tongue-shaped projection (9) extends via a slit (15) into a recess (14) in the openable part. The projection (9) will thus be partly visible from the upper side of the opening arrangement until such time as the moving part (4) has been displaced to an open position in which the projection (9) irreversibly departs from the recess (14) and gives a clear, visual indication that the opening arrangement has previously been opened.

Abstract: A method and apparatus for transferring tabs to a continuous material web in connection with the manufacture of packaging material in conversion machines includes the use of a transfer wheel which is located between a supply station for tabs and a deposit station, in which the wheel is located in contact with the packaging material web. With the aid of retainer jaws displaceable in a circumferential direction of the wheel, and fixedly disposed abutments, the position of each tab transferred to the wheel is corrected before the tab reaches the deposit station, so that the transfer to the packaging material web takes place in accurate register with markings previously provided on the web. The method and apparatus is well-suited for use in connection with continuous material webs travelling at high rates of speed, such as 400 to 500 meters/minute.
