Abstract
Abstract A photographic copying machine wherein the copying station is located between two feeding stations for a web of photographic material. The web is guided by fixedly mounted and pivotable guide members which define at each feeding station an opening through which loop-shaped intermediate portions of the web can enter a basket-shaped magazine. Two intermittently driven wheels at the first feeding station draw the web from a supply cassette and feed it directly into the adjacent magazine from which the web is withdrawn by intermittently driven wheels at the second feeding station whereby the web enters the other magazine from which it is withdrawn in response to rotation of the takeup reel in a second cassette. Pivotable flaps can seal the magazines from the path for the web during threading of the leader of a fresh web into the copying machine, and forked intercepting devices are provided adjacent to the magazines to intercept folded-over portions of the web.

Claim 1
Independent Claim
211 words
In a photographic copying machine wherein a web of photographic material is advanced lengthwise in a predetermined direction along an elongated path, a combination comprising a plurality of first guide members flanking said path at opposite sides and defining an opening through which an intermediate portion of a web in said path may extend from said path; a magazine adjacent to said opening and positioned to receive that intermediate portion of a web in said path which extends from said path through said opening, said magazine having confining means contacting one side of the web portion in said magazine; first transporting means located ahead of said opening, as considered in said direction, and arranged to feed the web lengthwise so that the length of the web portion in said magazine increases when the rate at which the web is being fed into said magazine by said first transporting means exceeds the rate of withdrawl of the web from said magazine; second transporting means located downstream of said opening and arranged to intermittently draw the web from said magazine; and a second guide member movable between first and second positions in which said second guide member respectively prevents and permits the web in said path to enter said magazine through said opening.

A combination as defined in claim 8, wherein a line which is tangent to and is disposed between said rotary members extends into said opening.
Claim 11
Dependent Claim
54 words
A combination as defined in claim 1, wherein said guide members define a second opening located downstream of said second transporting means and further comprising a second magazine adjacent to said second opening and arranged to receive a portion of a web in said path in response to operation of said second transporting means.
Claim 12
Dependent Claim
