A method for producing a fluid trap for an instant film assemblage, which
method can produce an environment-friendly trap easily and at low cost, is
disclosed. A plate-shaped paper material having a uniform width and a
uniform thickness is passed through a clearance formed between a pair of
rollers. The plate-shaped paper material is compressed at
width-directional opposite end portions thereof such that a thickness of
the paper material gradually decreases from a central portion thereof
toward opposite ends thereof, and at the same time, the paper material is
cut along a longitudinal direction thereof to a predetermined width.
Thereafter, the paper material is cut along the width direction thereof at
predetermined intervals with respect to the longitudinal direction
thereof, thereby producing the trap.
