(57) A reduction to the traveling motion of bottles (B1) along a delivery conveyor (12)
in an intermittent motion decorating machine (10) is provided by one (66,68) of a
pair of workpiece feed cams (66,68;70,72) rotatably supported in a side-by-side relation
to rotate about spaced horizontal axes lying in a common horizontal plane. The workpiece
feed cams (66,68;70,72) have feed cam tracks (66A,68A) for receiving cam followers
(74,75) of each of plurality of horizontal bottle carriers (76). One of the feed cam
tracks (66A,68A) reduces the speed of the bottle carriers (76) from a relatively high
entry speed corresponding to the through put speed in the decorating machine (10)
to the speed of the deliver conveyor for more densely populating the delivery conveyor
(12) with workpieces (B1). Carrier transfer members (52,53,54,55) at each of opposite
ends of the workpiece feed cams (66,68) transfer the bottle carriers (76) from one
to the other of the workpiece feed cam (66,68). A drive (14,15,21,38) rotates the
workpiece feed cams (66,68), carrier return cams (70,72) and carrier transfer members
(52,53,54,55). The decorating machine (10) is provided with a registration station
(R) preceding spaced apart decorating stations (P1-PN). The registration station (R)
includes a drive to reduce the clamping pressure by chucks (79) on a workpiece (B1)
while establishing a predetermined orientation of each workpiece (B1) relative to
the decorating stations (P1-PN).
