Method for lubricating pressure relief valves
A method for applying a lubricant to a pressure relief valve during the process of applying the pressure relief valve to packaging. The method includes temporarily separating layers of the valve with a vacuum applicator when the lubricant is applied. A pressurized nozzle sprays or atomizes the lubricant into the valve opening. Graphite suspended in liquid silicone is used as the lubricant; it is recirculated in a reservoir to keep the graphite in suspension. Optical sensors check for valves before the entrance to, and after exit from, the vacuum applicator.
Method and apparatus for making bags
A machine and method for making bags is described and includes a web, traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have, connected thereto, a source of power that is at an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire may be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.
Cup-forming process and machine
A cup-forming machine includes having a male mandrel and a female receiver. The male mandrel uses a cup body blank and a floor blank to form a body of a cup. The female receive receives the body and forms a rolled brim on the body to establish a cup.
Method and Device for Thermal Activation of Packaging Sleeves
A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.
Container, Method of Making a Container, and Apparatus for Manufacturing a Container
A container that comprises an outer shell and an inner pouch. The outer shell is made of a paperboard material and it comprises a side wall and a base element, the side wall including a main body portion, a neck portion, and a tapered or curved shoulder portion. The inner pouch is secured to a fitment, and is supported within the shell by the fitment engaged with the neck portion of the shell so that the pouch extends into the main body portion of the shell. The side wall is formed from a single blank that is formed from a flat sheet of paperboard and that includes a single main body panel and a plurality of neck panels extending from the main body panel.
SYSTEMS AND METHODS FOR WEB-FED DRY FORMING OF FIBER-BASED PRODUCTS
Disclosed are methods and systems for production of fiber-based, plastic-free products are produced by a web-fed dry forming process. In some embodiments, a method of manufacturing a paper-based packaging product includes conditioning a paper web to optimize a moisture content of the paper web and to treat the paper web with at least one additive to form a conditioned paper web; and dry molding the conditioned paper web under one or both of heat and pressure to produce a plurality of finished paper-based packaging products.
System and method for forming a compostable pod for beverages from a sheet having a controlled moisture level
The invention relates to a system (100) for manufacturing a compostable pod (900) for brewing products. Therein, the pod (900) is made from a sheet (600) made of a biodegradable cellulose-based material. The system (100) comprises at least one shaping line (200), which comprises a handling unit (300) for transferring the sheet (600) along a transfer direction (TD) through the system (100). The shaping line (200) further comprises a humidifying unit (400) for moistening at least one side of the sheet (600) with a moistening agent (401), and a forming unit (800) for shaping a part of the moistened sheet (600) into a three-dimensional shape to form a pod element (910), which defines a pod cavity (911). The shaping line (200) comprises further a humidity sensor system (500) for visually sensing a level of humidity of at least a section of the moistened sheet (600). Values related to the level of humidity sensed by the humidity sensor system (500) are received by a control unit (700), which is further configured to control the humidifying unit (400) based on these values. The invention also relates to a method for manufacturing a compostable pod (900), whereby a level of humidity of at least a section of the moistened sheet (600) is visually sensed and forwarded for controlling the moistening process of the at least one side of the sheet (600) correspondingly.
PRODUCTION METHOD AND PRODUCTION SYSTEM FOR FIBER BASED CELLULOSE MATERIAL PRODUCTS
This invention relates to Production method for fiber based cellulose material products by means of converting a blank or web, wherein there is provided a production space (1) including a converting production unit (2) intermittently producing a shaped product (5B), a supply station (3) and a supply path (4), comprising the steps of: a. Providing a supply of unconverted blanks or a web (5) at said supply station (3) having a density below 0,5 kg/dm.sup.3 and a wet content below 20% weight. b.
