The slide frames consist of plastic material and are supplied ready for use. The film is fed in steps to a cutting device for severing the leading film section. The film section severed by the cutting device is gripped in the cutting station by a plierlike gripping device and in this position, without being pivotally moved through 180.degree., is inserted as far as possible for projection into the internal space of a frame, which is held ready in an expanded or unfolded position. The film section is held in this position for projection until the expanded or unfolded frame part is released. Two protective strips of transparent material, such as polycarbonate, are fed on respective sides of the film strip before the cutting device. The protective strips have for each feeding step at least one perforation hole, which is aligned with a perforation hole of the film strip. The two protective strips sandwiching the film strip are subjected to the same process steps as the film strip in unison therewith.
A process of cutting developed film strips into film sections and of immediately subsequently introducing said sections into slide frames made of plastic material supplied ready for use, comprising feeding two protective strips of transparent material on respective sides of a film strip in a series of intermittent feeding steps, said protective strips having for each feeding step at least one perforation hole which is aligned with a perforation hole of the film strip, the two protective strips sandwiching the film strip to form a sandwiched film strip, advancing said film strip in said feeding steps to a cutting device;
