A reciprocating transfer conveyer 72 is arranged to convey the articles from the conveyer 36 to a position further downstream, the drive of the conveyer 36 being made operative when an article is detected by the feelers 220 at the same time as a detecting means 224, 226, (Fig. 7), responds to a predetermined position of the carrier of the conveyer 72. The latter comprises an assembly of side-by-side longitudinally extending bars 72<SP>1</SP>, each of which has article engaging projections 74. The means 224, 226, comprises a switch operated by a cam shaft 106 controlling the transfer conveyer 72. When this switch and a switch 222 (Fig. 9) are both closed, a clutch 212 in the drive of the conveyer 36 is energized. The conveyer 72 is given a cyclic to- and-fro and up-and-down movement by a pair of parallel linkages 92, 94, 86, 100, disposed on respective sides of the conveyer. A cam follower 102 connected to the links 100, engages a cam 104 on a main drive shaft 106. The links 86 of the parallel linkage are each mounted to slide between respective sets of rollers 88 carried by the assembly of bars 72<SP>1</SP>. A further component of movement of the bars 72<SP>1</SP> is provided by a rod 128 pivotally connected at one end to the cam 104 and at the other end being connected to a lever arm 130. The other end of the arm 130 is pivotally connected to a slider mounted for movement in a slot 134 of a member 136, depending from, and rigid with, the assemblage of the carrier bars 72<SP>1</SP>. Between the conveyer 36 and the upstream end of the conveyer 72, is a high speed conveyer 38 for spacing the articles. The conveyer 72 carries the articles to a weighing head 56. The weight of the article is fed to a computer (26) (Fig. 1, not shown) which computes the price of the article and transmits this to a printer (28) (Fig. 1, not shown). The article is then conveyed by the carriers 72<SP>1</SP> on to live conveyer rollers 58 (Fig. 5). These carry the article up to a positioning rail 70 beneath the labelling head 151. The latter is connected to a rod 182 carrying a roller 172. The latter is engaged by members of the parallel linkage to result in its up-and-down movement. A roller 176 for pressing down the label is actuated by a rod 182 connected to a crank arm rigid with the shaft 124. Labels, each printed with a price according to information supplied by the computer (26), are fed between two series of opposed belts 140, 146, to the labelling head 151 from a feed shoot 144. The latter is grooved to correspond with the spacing of the belts 140 to provide a stiffening effect. A bellows 190 operated by a link 192, produces an air blast for transferring the label from the head 151 to the article.
