Abstract

Abstract This invention relates to an apparatus for extracting articles such as pharmaceutical tablets from faulty blister packs. Previous devices for performing this task could only accommodate one size of blister pack or could not easily be adjusted to cater for different sizes. By feeding blister packs between two cooperating rotating rollers (23 and 33), however, one of which (23) is provided with slideably adjustable dogs (53 and 55), blister packs of varying sizes may readily be deblistered.
