Abstract
Abstract The sheets in a column of compartments of a sorter, collator or the like are jogged to align their edges. An endless belt is moved past a glue dispenser to coat a length of the belt corresponding to the number of compartments to be covered. The belt is then moved into engagement with the edges of the sheets in those compartments to deposit the adhesive on the edges. The operation is then intermittently repeated along the edges of the sheets to bond the desired extent of the length of the edges. A jogging mechanism aligns and holds the edges in alignment for binding.
