  • two bearing sleeves to be provided which are significantly shorter than the bearing sleeve 31, the bearing sleeves being arranged opposite one another on the front ends of the slide body 12c.
  • the bearing sleeve 31 is provided as a separate machine element which is connected to the other components of the slide body 12c.
  • the bearing sleeve 31 can be formed in one piece with the slide body 12c.
  • the carriage body 12c is slidably movable along the sheet guide 11c by means of the bearing sleeve 31.
  • the bearing sleeve 31 is designed as a sliding sleeve.
  • the bearing sleeve 31 can also be designed as a basically known linear ball bearing, so that the carriage body 12c can be moved on the arc guide 11c by means of rolling bearings.
