THE P1CTU REGOE-R
the illustration below. If the film is to be nted it is placed for a short time in a similar tank Imtaining the colour — red, sepia, blue, or green, as may : desired.
The film is then sent to the drying room, where it taken off the reel and wound on one of the large lindrical drying drums, such as is shown on this ige. These drums are continually in motion to prevent ittling of water on the film, which would afterward :ow up in the form of spots. It takes about twenty inutes to dry a film.
Throughout the plant where the raw stock is handled
d in the drying room the temperature is always kept
the same degree by an air-conditioning plant situated
the roof of the building and operating through the
ors, which are hollow. The air is drawn in through
aperture by a fan, passing through a spray which
'iishes it, then over pipes which may contain steam or
» water, and through an aperture which may contain
A, all according to the original temperature of the
sr, whether it is necessary to lower or raise it. This
lane fan propels the air through the hollow floor into
tp room where it circulates and is withdrawn by another
JBi pioviding a suction. The temperature is regulated
■tomatically by a thermostadt and placed in every
»m, and is connected to a well. Should any change
jliur this thermostadt automatically rings the bell.
When the film has been thoroughly dried, it is removed |mm the drum in big baskets and sent to the cutting rim, where it is assembled.
j ft.ll of this work is done, not on one print of each film, tit on every print ; and since there are usually one bndred prints made of each picture, five hundred thou«id feet of film must pass through all of these processes m every separate picture play. Charles Carter.
