Abstract
A strapping apparatus for securing a tape around a package has a housing, a support roll rotatable on the housing, a tube shaft pivotal on the housing adjacent the support roll about a tube-shaft axis, and a drive shaft rotatable in the tube shaft about a drive-shaft axis parallel to and offset from the tube-shaft axis. A first drive roll on the drive shaft carries a friction layer bearing axially offset from the drive-shaft axis on the housing. A first drive connected to the drive shaft rotates same and the first drive roll in a clamping direction and thereby oppositely rotates the tube shaft about the tube-shaft axis into an end position and also can rotate the drive shaft and the first drive roll in an opposite freeing direction to thereby oppositely rotate the tube shaft about the tube-shaft axis into another end position.
