Abstract: A strapping machine has a housing carrying a mount attachable to an overhead balancer line, tensioning and sealing devices in the housing, and an elongated pivotal handle. An inner handle end is formed with an annular inlet passage and a radially throughgoing inlet port opening into the inlet passage. The handle also is formed with axially extending passages extending from the inlet passage to an outer handle end. A pneumatic motor in the outer handle end drives a transmission in the inner end of the handle in turn drives the devices in the housing. An inlet fitting on the housing is connectable to a compressed-air supply line. A conduit has one end communicating with the inlet fitting and an opposite end opening radially inward into the inlet port of the handle. The outer handle end is formed with an outlet opening for venting air from the motor.

Abstract: A C-section ring fixed on a steel-mill roll and coaxially surrounding its stub has inner and outer axially extending legs defining an axially open cavity. The inner leg is tapered away from the roll and is formed adjacent the free end with a radially outwardly open annular groove. An annular cover part fixed on a stationary support, engaged in the cavity, forming a drain compartment open axially away from the roll, and formed with a radially outwardly open catchment groove radially aligned with a free end of the inner leg is also formed with a passage extending from the catchment groove to the drain compartment. An annular extension on the cover part has an inner surface carrying a seal ring that bears radially inward on the stub. An add-on part on the extension forms with the extension, with the cover part, and with the C-section ring a labyrinth.
