along the panel 2 at this place there is mounted a roller 6 along the inner side edge of the roller table and a first working unit 8 has a receiving table 10 located immediately outside this roller thus the wheel can simply be drawn or pushed onto the table 10 aided by the roller 6 providing for a rolling support the unit 8 is a bead breaker serving to press the upper tire bead downwardly from the rim by means of an upper pressing tool while the table 10 is rotating when it is required to break also the opposite bead e g for a complete tire change the operator can turn the wheel upside down on the table 10 merely by tilting over the wheel without actually lifting the entire wheel alternatively of course the unit 8 could be designed so as to effect a bead breaking even at the lower side of the wheel the following unit designated 12 is a tire changer having a rotary wheel supporting table 14 and an upper tool 16 for heeling the tire bead over the rim edge as well known in the art the unit 12 is placed so close to the unit 8 that the wheel can be transferred simply by sliding or tilting over again without being carried as a whole when the repair or tube or tire change has been effected at the unit 12 the wheel will then be correspondingly easily transferable to the subsequent unit designated 18 which is an automatically operating inflation unit as such already known in the art however it is here designed as a flow through unit comprising a roller table bottom 20 fig2 for easy reception and delivery of.
