Abstract: The present disclosure relates to speed change kits adapted to allow converting lines to be reconfigured to operate at different speeds. In one form, a system for fabricating disposable absorbent articles includes a plurality of converting modules; a plurality of absorbent article converting mechanisms; and a speed kit. The plurality of absorbent article converting mechanisms can be configured from a first configuration to a second configuration by modifying the plurality of absorbent article converting mechanisms to include the speed kit. In the first configuration, the plurality of absorbent article converting mechanisms operate to produce absorbent articles at a first speed range; and when in the second configuration, the plurality of absorbent article converting mechanisms operate to produce absorbent articles at a second speed range different from the first speed range.
