indications on the selvedges of clothare already
known; in such machines the cloth, which is al

In order to show the working of the selvedge
printing apparatus, the latter is represented in
Fig. 1 applied to a felt-cloth calender, a so-called
Palmer, for ?nishing woven fabrics. I is the
45 frame of such a Palmer, 2 is a heated cylinder, 3
a guiding cylinder for the felt-cloth 4, and 5, 6, 1,
8, 9, Ill, II and I2 are guiding rollers for the
felt cloth. The fabric I1 runs through the Palmer
between the heated cylinder 2 and the felt cloth
50 4, and is conducted over the guiding rollers l3, l4,
l5, I6 and on its way one selvedge is marked by
the stamp of the selvedge-printing apparatus,
mounted on the supports I8, which are ?xed to
the Palmer.
These supports l8 carry a shaft l9, on which is
stamp track.
The stamp-ink is poured in the box 36 and is
taken from there by a system of rollers 31, 38,
39, 40, 4!, driven from the shaft I9 by means of
the chain-wheels 42 and 43, the small shaft 44
and the toothed spur-wheels 45—46. These roll 45
ers 31-4! grind well the ink and transform it
into a thin ?lm, which is applied evenly on a
swinging’ roller 41, which by means of the cam
38, the ‘double lever 49 and the connecting rod 50
is oscillated about the pin 5|. The cam 48 is so 50
formed that the swinging roller 41 is brought
to a point in the track of the stamp before the
stamp arrives at that point. To the bearer 20 on
the side of the stamp 2| is screwed a segment
like piece 52, the track of which has exactly the 55
diameter as the‘track or ‘the stamp; this
