Abstract

Abstract A simple and inexpensive apparatus for splicing two web ends such as photographic film, comprises a table, a pair of removable and replaceable tracks to be placed on top of the web, a pair or removable and replaceable magnetic clamping strips to be placed on top of the web between the tracks, a motor driven carriage moveable along the tracks, and a pivoted ultrasonic transducer on the carriage having a floating horn for uniting the web ends. The carriage is driven by a motor actuated pinion gear which engages a rack on one of the tracks. Removable and replaceable abut,end members are provided for properly positioning the clamping strips and the web ends. The table can be in the form of a cantilever to permit a loop of web to have its two ends spliced together.
