A machine for covering mattress cores of foamed material, rubber and polyester featuring two perpendicularly disposed drive belts whose width corresponds to the height of the mattress and which converge in the direction of travel of the mattress, the disposition of the aforementioned drive belts permitting the mattress core to be compressed throughout its width enabling fabric to be pulled up on the nozzle without difficulty as sticking of the mattress core to the inside of the nozzle during the covering process is prevented. Furthermore, laterally disposed drive belts are employed such that the corners of the mattress core leave the nozzle first and thereby fill out the corners of the cover fabric in the correct position eliminating time-consuming adjustment and beating into desired shape and appropriate height and width adjustments make it possible for the same machine to cover mattress cores of different widths and thicknesses.
