Abstract: The apparatus for placing decorative or protective sleeves of heat-shrinkable plastic over objects which do not easily stand upright. The machine comprises a device to place sleeves vertically over intermediate pins, of suitable diameter, fastened to an endless chain. The pins are brought into horizontal position during the returning of the chain around a wheel inclined at 45.degree., to circulate in alignment with objects received individually in housings provided on a second endless chain driven at the same linear speed as the first. A cam mechanism is then started to transfer the sleeves of the pins to the objects with which they are aligned.
