053375800 | By means adapted to engage overlapped seam | 9 |
20140260088 | ULTRASONIC WELDING DEVICE - An ultrasonic welding device for the transverse welding of a continuous chain of package blanks movable in a longitudinal direction, the continuous chain of package blanks including a continuous succession of products spaced apart in a longitudinal direction and wrapped in a tubular packaging film. | 09-18-2014 |
053375900 | With means to heat or cool seam | 8 |
20100043352 | LONGITUDINAL SEALING MECHANISM - A longitudinal sealing mechanism is adapted to seal an overlapped portion of a packaging material formed into a tubular shape with the overlapped portion extending along a conveying direction of the packaging material. The longitudinal sealing mechanism includes a contact section, a heating section and a receiving member. The contact section comes into contact with the overlapped portion of the packaging material. The heating section heats the contact section to perform longitudinal sealing of the overlapped portion to form a longitudinal seal portion. The receiving member abuts against the contact section with the overlapped portion of the packaging material being disposed therebetween. The contact section, the heating section, and the receiving member are arranged such that an amount of heat per unit time applied to the packaging material from the contact section decreases in a direction toward both sides of the longitudinal seal portion. | 02-25-2010 |
20100107560 | PACKAGING TUBE FOR A PREDETERMINED VOLUME OF A BIOLOGICAL SUBSTANCE TO BE STORED AT A LOW TEMPERATURE AND SYSTEM INCLUDING SAME - The invention relates to a packaging tube for a pre-determined volume of a biological substance to be stored at a low temperature and to a system including same. The inventive packaging tube comprises a portion ( | 05-06-2010 |
20110214392 | HEAT SEALING MACHINE FOR A PACKAGING SYSTEM - In a system for discretely packaging liquid or solid medication or other substances comprising a compartmented tray ( | 09-08-2011 |
20130239519 | EASILY REMOVABLE SELVAGE DEVICE - The problems associated with the prior art have been overcome by the present invention, which describes a device for spooling selvage as it is cut by a side-sealing machine. The device includes a two part core, which is held together by a friction fitting, such as a keyless bushing. The two parts of the core are shaped so that as the selvage is wound onto the core, it exerts both a radial and axial force on the core. This axial force provides the force needed to separate the two parts of the core when the bushing is removed. Various shaped core parts may be used, and various friction fittings are also envisioned. | 09-19-2013 |
20130326995 | ELECTRICALLY OPERATED MACHINE FOR COVERING BOOK COVERS AND SEALING ENVELOPES AND ARTICLES OF VARIOUS KIND - A machine is described for covering book covers and sealing envelopes or articles of various kind. The machine comprises a fixed lower base suitable for resting a sheet of flexible plastic material for an article to be covered, an upper part movable towards said base and a heatable blade accommodated in the upper part to execute soldering of the overlapped ends of the plastic material sheet along the article edges when the upper part is approached to the lower base. The machine comprises an electric motor, a control member accessible from the outside of the machine for operating the electric motor and movement transmission means acting on the sides of the upper part to induce, at every activation of the electric motor, movement of the upper part towards the lower base for executing the soldering of the ends of the plastic material sheet. | 12-12-2013 |
20140069056 | Apparatus for producing heat-shrinkable packaging with integrated hand-hold - Apparatus for producing heat-shrinkable packaging with an integrated hand-hold with a circuitous path extending from an input loading/unloading zone, a section where the open portion of a heat-shrinkable bag is sealed shut and creating a container in which an object is enclosed, a section in which heat is applied directly to exposed areas of the plastic film of the package for sealing the package, and a section of path enabling the package to cool; trolley apparatus for supporting the package and engaging the circuitous path for movement of the package along the circuitous path; and protrusions positioned along the circuitous path for propelling the device along the designated track route. | 03-13-2014 |
20140090337 | VERTICAL PACKAGING MACHINE FOR FOOD PRODUCTS - A packaging machine comprising a transversal sealing unit ( | 04-03-2014 |
20140215966 | SEALING MACHINE AND THE PROTECTING STRUCTURE FOR THE SAME - A sealing machine and the protecting structure that fit a wide range of sealing conditions and plastic bag materials, and prevent the plastic bag from breaking around the sealing line due to excessive fusion and tension are disclosed. The sealing machine comprises a pair of block members, each block member is disposed with an electrical heating wire, each electrical heating wire is covered with a first protecting belt, and each first protecting belt is covered with a second protecting belt. Each first protecting belt or second protecting belt comprises a plurality of apertures. | 08-07-2014 |
