20150174815 | Thermoforming machine and method of instituting a format change - Format change method for a thermoforming machine and a thermoforming machine. A station of the machine includes an upper tool and a lower tool, at least one of the upper and lower tools being suitable for moving in a substantially vertical actuating direction during the operation of the machine. In the method, the upper tool is supported on the lower tool and both tools are subsequently withdrawn from the station and are replaced with new tools. When withdrawing the upper and lower tools from the station and when introducing the new tools therein, the tools are moved simultaneously and jointly in a replacement direction different from the actuating direction. | 06-25-2015 |
20150013274 | Product wrapping machine and operating method for a product wrapping machine - A product wrapping machine with a plurality of counter-jaws homogenously distributed in a forward movement direction (X), a plurality of jaws moving perpendicular to the forward movement direction (X) from an open position to a closed position against the counter-jaws for sealing together the films wrapping the product to one another and cutting them. The machine also includes a jaw actuator for each jaw causing the corresponding jaw to move in the closing direction. The jaws move together simultaneously in the forward movement direction (X) and move independently from one another in the closing direction. The machine further includes a tensioner suitable for collecting part of the film wrapping the product when a jaw leaves the closed position. | 01-15-2015 |
20140033647 | APPARATUS AND METHODS FOR PACKAGING A PRODUCT - A packaging machine having a sealing member that acts on a product wrapped by a lower film and an upper film, and which seals or closes the films to each other around the product in order to vacuum-package said product between both films, and control means for causing the sealing member to move in order to package the product. The sealing member defines at least one inner space where the product to be vacuum-packaged is disposed wrapped at least partially by the two films. According to one implementation the sealing member includes at least one longitudinal first wall, a longitudinal second wall and a transverse wall between which the inner space is defined, and an unobstructed opening facing the transverse wall. | 02-06-2014 |
20130298505 | Method for operating a vertical packaging machine and vertical packaging machine - According to some implementations a packaging operation is provided that includes a stage for the continuous feeding of a laminar film, a stage for the forming of the laminar film with a laminar tube being obtained, and a drive stage in which by means of at least two drive belts the movement of the laminar tube is caused. The packaging operation also includes a control operation in which the position of the drive belt in relation to the forming tool is controlled when slippage or risk of slippage of at least one of the drive belts with respect to the laminar tube is detected. | 11-14-2013 |
20110088354 | Packaging Apparatus and Processes - Systems and processes for packaging a product. In one implementation a process involves transporting the product in a first direction, printing information on a film by use of a first printer prior to the film being applied to the product, the film having a width that is less than a width of the product and shrinkable only in a longitudinal direction. In one implementation the film is then applied to the product to produce at least a partial film sleeve around at least a first portion of the product as the product is advanced in the first direction. In one implementation heat is then conveyed to at least a section of the film applied to the product to cause the film to shrink in the longitudinal direction. | 04-21-2011 |
