A method of supplying cartons to a carton-packaging machine, comprising the steps of providing flattened cartons stacked in a line in a container package so that two cutouts on the cartons are lined to form two grooves on two parallel sides of the cartons; inserting two bar-shaped forks into the grooves respectively in the stacking direction of the cartons; pressing the cartons to be together along the inserting direction of the bar-shaped forks by pressers, which are adjustable for a different stacking amount of the cartons, so that the cartons are placed at the central portion of the bar-shaped forks; pulling out the cartons from the package with the bar-shaped forks; and supplying the cartons to the carton-packaging machine with the bar-shaped forks.

The invention provides a spool for winding a photographic roll film. The spool has a bar-shaped spool core which is slitted to lengthwise direction to form a slit for inserting a tongue-shaped end of the film having a through hole. On an inside wall of the slit, there is provided a catch claw capable of engaging the through hole. On another inside wall opposite to the above inside wall, there is provided a pressing rib for pressing and guiding the tongue-shaped end to the catch claw. A part of the outer surface of the spool core, adjoining to the inside wall of the slit in which is disposed the pressing rib, is shaped to serve as a film contact surface. The tip surface of the pressing rib and the film contact surface both jointly form a continuous shape of a circular arc.

A process for the continuous preparation of slides to be chemically analyzed comprises forming regularly a plurality of hollows on an advancing web material; putting a piece of film to be chemically analyzed in each of the hollows; sticking a long covering member having a plurality of apertures corresponding in their positions to the hollows on the web material onto the surface of the web material so that the apertures and the hollows on the web material are in registration; and cutting the circumference outside of each of the hollows. Also disclosed is a slide to be chemically analyzed which comprises a web material having a hollow in the central region thereof in which a film to be chemically analyzed is put, a covering member having an aperture on the surface thereof stuck to the web material; and downwardly extending flanges on a circumferential portion of the slide having heights substantially equal to that of the hollow to stabilize positioning of the slide.
