Cement splicers

Cement splicers join films together by using a chemical called

film cement Film cement is a special glue designed to join motion picture film. It is made of film base dissolved in a solvent. Two cut sections of film are spliced together in a film splicer using film cement. Splices can be made either with a "hot" splicer, ...

Thermal paper splicers

Used in film processing labs to join film into large rolls before processing. These use a plastic coated tab to make the splice. The tab is heated and the plastic melts slightly, bonding to the film. The tabs are often printed with a number or bar code to identify the film after processing.
