A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

The invention relates to a device (1) for machining a workpiece (2) which preferably consist at least in sections of wood, wood material or synthetic material and/or for coating the workpiece (2) with a coating material (4), comprising: a machining device (30, 40) for machining the workpiece (2), and a conveyor (20) for affecting a relative movement between the workpiece (2) and the machining device (30, 40), a controller for controlling the conveyor (20) and the machining device (30, 40), characterized in that the device (1) further has at least one workpiece measuring device (22) which is configured to measure at least one property of the workpiece (2), in particular a property of a surface (2) of the workpiece (2) to be machined or to be coated.

A machine for packaging articles includes a frame; a feeder feeding film to a packaging station to wrap articles. A sealing unit includes at least two sealing elements movable relative to each other between a spaced-apart position and a close-together position where the two sealing elements cooperate to seal the film interposed between them. First and second mechanisms having first and second motors move the sealing unit. The second motor is operatively coupled to at least one of the two sealing elements. The first and/or the second mechanisms include at least one articulated arm, respectively. A control unit is operatively connected to the first motor and to the second motor to drive them in proper relationship to move the two sealing elements relative to each other and relative to the frame according to a predetermined law of motion.

A method for welding two hollow profiled rods made of plastic to form a window frame. The profiled rods to be joined together are heated to a predetermined temperature by inserting a welding plate between their connecting surfaces and pressing the same against the welding plate, forming outer and inner beads, and the profiled rods are pressed together under pressure after removing the welding plate, with a simultaneous increase in the size of the weld bead. For all cross sections of the profiled rods and the plastics used for manufacturing the window frames, to obtain a type of shadow groove on the top side and/or front side and on the bottom side and/or rear side of the finished window frame in the area of or near the connecting sites of the finished window frame, only the outer beads formed on the visible surface of the subsequent window frame in the area of or near the connecting sites of the two profiled rods are pressed slightly inward after removing the welding plate forming an oblique edge, and then are removed together with the inner beads, and then the connecting surfaces of the two profiled rods are joined together.

A process for producing a flexible container is provided. The process includes: A. providing a rear panel web, a front panel web, a first folded gusset panel web, and a second folded gusset panel web, each panel web having peripheral edges and a bottom face, each bottom face having two opposing tapered edges meeting at a bottom end; B. placing the folded gusset panel webs between the rear panel web and the front panel web, the gusset panel webs opposing each other, the panel webs configured to form a common periphery and the bottom seal area including the bottom end of each panel; C. first sealing the peripheral edges, the tapered edges, and the bottom seal area under a set of heat seal conditions; D. second sealing a portion of the bottom seal area under a second heat seal condition; and E. forming a flexible container.

A method for the sterile connection of pipes, consisting of: providing a first and a second pipe; a separating area of the first and second pipes is heated; both pipes are mechanically separated by exerting traction and/or shear force onto the pipes so that both pipes are respectively separated in the heated separating area; after the pipes are separated, a mechanical contact between the end of the first pipe section of the first pipe formed by the separation of the first pipe is established with the end of the first pipe section of the second pipe, formed by the separation of the second pipe, and mechanical contact is established such that the ends of the pipe sections still have, following heating when they come into mechanical contact with each other, a temperature such that they form a material fit connection without additional heating after separation.

A sonotrode that includes a sealing face; a front quarter wavelength region adjacent to the sealing face, wherein the front quarter wavelength region has been modified to increase the gain of the sonotrode; and a rear quarter wavelength region adjacent to the front quarter wavelength region, wherein the rear quarter wavelength region has been modified to create a non-uniform amplitude profile across the length of the sealing face of the sonotrode.
