Adjustable automatic case tapers can tape many sizes of cases. An adjustable case taper must be adjusted by an operator each time a different size case is used. Other than the adjusting, this type of case taper is automatic; it tucks and tapes the flaps. An adjustable automatic case taper is useful in operations when several of the same size cases are going to be used at once, but a different size case may be used later in the day.
