An ultrasonic module for use in package sealing systems that includes a moveable front jaw; an elognated sonotrode disposed within the front jaw, wherein the sonotrode includes an elongated sealing face, and wherein the width of the sealing face is at least 12 inches (30.48 cm); a moveable rear jaw; and an anvil mounted on the rear jaw opposite the sonotrode, wherein the anvil mechanically cooperates with the sonotrode to seal a package.

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.

The invention relates to a sealing body, where heat-producing elements of a heating element are contacted from the rear side thereof. Other aspects relate to a sealing body where the site of the heat production and the site of the heat dissipation (i.e. the point of action) are as close to each other as possible. Other aspects relate to a sealing body comprising a heat element with a built-in temperature sensor. Other aspects relate to a sealing body with a defined sealing contour. Other aspects relate to a sealing body having a three-dimensionally structured contact surface. Other aspects relate to a sealing body with a circular, annular, or strip-type heat element. Other aspects relate to a sealing body with built-in electronic circuits. Other aspects relate to a sealing body that can cool the heating element as required. Other aspects relate to a sealing body that can suck up the material to be welded.

A protective packaging formation device is provided herein. The device includes an inflation assembly having a fluid conduit that directs fluid between overlapping plies of a polymeric web. The device also includes a driving mechanism that drives the film in a downstream direction. The device also includes a sealing mechanism that includes a thin film heater that heats the plies to create a longitudinal seal that seals the plies of film together. The driving mechanism drives the web such that the web slides across the heating assembly in a downstream direction to trap fluid between the plies.

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

One embodiment of the present invention includes an apparatus for securing a wrapping material around an item, such as a baled agricultural item, the apparatus including a main plate and at least one projection, the projection including a heating element and a height adjustment mechanism, wherein the height adjustment mechanism controls a force applied to the wrapping material by the projection and provides a force for moving the projection.

A welding head comprises a welding element for welding a lid to an opening device of a container, a supporting body for supporting the welding element and a compensating device for compensating a possible mutual mispositioning of the welding element and the lid during welding of the lid to the opening device, the compensating device being interposed between the supporting body and the welding element, the compensating device comprising a planar spring arrangement provided with at least one planar spring element having a first member and a second member mutually connected by deformable elements.

A device to package a sterile bulk product, particularly, a dermocosmetic or galenic preparation, into a container. A sterile enclosure of the device includes a hopper containing the bulk product. The hopper includes in an axial direction, a cylindrical reservoir part and a pouring part connected to the cylindrical part. A transfer device transports the container under the hopper to fill the container in a filling zone. A blower provides ultra-filtered air from the ceiling to the floor of the enclosure, to produce a protective flow of air around the filling zone. The axis of the pouring part with an asymmetrical conical shape is not in line with the axis of the reservoir part such that the pouring opening is shifted towards the outer wall of the reservoir.
