Abstract
A tensioning and sealing apparatus for strapping an object (2) with a plastic band (1) includes a housing (3) having a tensioning unit (4) for retaining two ends (6, 7) of the plastic band (1) which are to be sealed and for tensioning the same and having a sealing unit (5) for connecting the two mutually overlapping ends (6, 7). The tensioning unit (4) has a tensioning shoe (10) and a toothed tensioning wheel (13) which is mounted on a pivotable rocker (11), which can be driven via a tensioning shaft (12), and which is intended for pressing the plastic band (1) against the tensioning shoe (10) and for gripping the same upon rotation. The bearing (15) of the pivotable rocker (11) is arranged on the side of the tensioning shoe (10) and behind the latter in the tensioning direction (14), the rocker axis being located between a bearing surface (16) of the tensioning shoe (10) and a base plate (8). The result is that the rocker (11), with the tensioning wheel (13), on the one hand exerts a sufficient press-on force on the plastic band (1) to be tensioned, and on the other hand can be raised again in any position of use of the apparatus without a great deal of force.
