Labelling machine comprising a cylindrical vacuum drum, a feed screw located in relation to the vacuum drum to move cylindrical containers from a starting point to a release point past the vacuum drum with their cylinder axes parallel to the cylinder axis of the vacuum drum and in tangent contact with the vacuum drum, and a continuous drive belt located to contact the sides of containers opposite their sides in contact with the feed screw, said belt serving to spin the containers from the starting point to the release point.

In a machine for applying segments of sheet or film material to the cylinder surfaces of cylindrical articles, such machine including a rotatable, cylindrical vacuum drum capable of receiving such segments on its cylinder surface, holding each segment on such surface while rotating, and releasing each segment to the cylinder surface of such an article as it moves past and in tangent contact with the cylinder surface of the vacuum drum, the improvement which comprises: (a) a helical article feed arranged to transport such articles with their cylinder axes parallel to the cylinder axis of the vacuum drum in a linear path past the cylinder surface of the vacuum drum, such helical artical feed being spaced from said drum surface such that each container, as it moves past the vacuum drum, is pressed into tangent contact with a segment on the drum and (b) endless belt means arranged to contact the surface of such container opposite the container surface in contact with the helical article feed (c) such helical article feed and endless belt means defining and forming a path of container travel commencing substantially in advance of such tangent contact of the article wih the vacuum drum and terminating substantially beyond such contact, whereby each container is caused to travel linearly at the desired speed and to spin about its cylinder axis at a desired speed without substantial acceleration or deceleration until such segment is firmly applied to the cylindrical article. A method of applying segments of film or sheet material to the cylinder surfaces of cylindrical articles which comprises: (a) providing a cylindrical vacuum drum capable of receiving such segments successively at a segment receiving station, holding each segment on its cylinder surface and transporting the thus held segment, by rotation of the drum about its cylinder axis, to a segment applying station (b) operating said vacuum drum as set forth in step (a) (c) transporting such cylindrical articles in succession with their cylinder axes parallel to the cylinder axis of the vacuum drum, such transporting being through a straight line path from a first location to a second location, such path being so positioned that between the first location and second location each container is brought into tangent contact with the leading end of a segment on the drum, such contact occurring a substantial distance from the first location and from the second location and (d) imparting to each container while it is being transported from the first location to the second location a spinning motion about its cylinder axis, whereby each segment, in turn, is released by the vacuum drum, picked up by the container and wrapped around the container at least partially while the container is undergoing simultaneous linear movement and spinning motion.
