This is an above view of a system in which tin cans arrive via conveyor (1) to a "feeding star" ("подающая звезда" in Russian; No. 5) and are placed firmly in slot 4. (source in Russian)

What does one call this "feeding star" in English?

I'm actually translating a text about a pharmaceutical filling-and-capping line, in which there is a "feeding star" and a "stoppering star". My text comes with no drawings, but I googled and found out that these "stars" are basically star-like cogwheels that take something from a moving conveyor system and position it precisely for further use. In my text, this "feeding star" probably passes drug-filled vials to the "stoppering star" which is part of the vacuum-operated automatic stoppering unit.

Looks like it may be called starwheel feeder or starwheel infeed - here's an excerpt from Design of Automatic Machinery:

Sprocket is one possibility, a feed or delivery spider are other possibilities.

The "feeding" and "stoppering" seem to be just literal Russian-to-English translations of "filling" and "capping," which would be good technical terms in English.

I would call the "star" an "escapement" by analogy with mechanical clocks etc - it forces the cans to move one at a time in a controlled manner, in the same way that at clockwork escapement allows a gear wheel to move one tooth at a time.

"Escapement" seems to be used in this context in several US patents for can filling devices that operate on one can at a time, though I couldn't find one that used the same "star" type of device.
