    摘要: A unit for sealing filter bags for products for infusion comprises at least: a shaped revolving roller (2) with circumferential and radial tracks (3, 4) that act as guides to make longitudinal and transversal contact seals on a web (5) of filter paper folded onto itself and moving under the roller (2), using sealing sonotrode means (6) arranged in sealing position under the roller (2) and close to the moving web (5) in such a way as to form) a tubular web of filter paper with a succession of substantially flattened filter bags formed on it; the sealing sonotrode means (6) being operated upon by fluid-driven means (7) designed to control, through appropriate means (8), the variable constituted) by the contact force and/or the distance between the sealing means (6) and the roller (2).

    摘要: Drive device for a handheld heater unit for welding plastic sealing webs and sheets, which is equipped with a heater device for heating the plastic sealing webs and sheets which are to be welded. The drive device has an elongate housing with a pressure-exerting and driving roller, by means of which the joining force can be applied in the vertical direction with respect to the plastic sealing webs and sheets. Furthermore, there is a coupling unit for joining the housing to the heater unit, in such a manner that the longitudinal axes of the housing and of the heater unit run substantially parallel to one another. In the housing there is a motor, which drives the pressure-exerting and driving roller, the height and/or distance of which with respect to the heater device is adjustable. The drive device together with a corresponding heater unit allows quicker, more accurate and therefore better-quality welding of the plastic sealing webs and sheets in manual welding applications, since the user only has to concentrate on applying the joining force. It is therefore possible to produce welds on plastic sealing webs and sheets on inclined and vertical walls, overhead, in U-shaped recesses or grooves and in corner regions.
