A catenary idler comprises a cable, a plurality of bearing surfaces disposed along a length of the cable, and a plurality of rollers disposed over the plurality of bearing surfaces. The plurality of bearing surfaces are fixed to the cable. The plurality of bearing surfaces may be a plurality of clamps. The plurality of rollers are rotatably supported upon the plurality of bearing surfaces. The cable may be rotatably supported at its ends. The catenary idler may include a first compression spring at a first end of the cable and a second compression spring at a second end of the cable. The rollers may be formed of an oil filled nylon. A conveyor belt impact bed includes a frame, a plurality of catenary idlers supported upon the frame, and a conveyor belt supported upon the plurality of catenary idlers.

A packaging machine for packaging products to be packaged using a stretchable film has a film transporter supplying the film. The film transporter has first and second belt conveyors that each have first and second transport belts, which are synchronously driven and arranged next to one another in a film transport direction. A belt conveyor is movable in a direction perpendicular to the film transport direction, and has a movable film guide to insert the film into the film transporter. The film guide has a guide plate for guiding the film. The guide plate has first and second recesses in an upper edge in the vertical direction facing the belt conveyors. The belt conveyors are to be inserted into a respective one of the recesses. The film transporter has cleaners for the belt conveyors.
