A wrapping module and a method for providing a sleeve around a mail item are disclosed. A sheet is folded over a leading edge of each mail item so that a first part of the sheet is folded against an upper side of the mail item and the second part of the sheet is folded against a lower side of the mail item and a third part of the sheet extends in the upstream direction beyond the trailing edge of the mail item. Glue is dispensed on the third part. The mail item is turned around with a turning station having a pendulum so that the third part of the sheet is folded around the mail item so that the third part is connected to the first part by the glue to form the sleeve.

An inserter hopper device for handling a pile of inserts includes a framework, a belly plate that is connected to the framework, a carry-down cam assembly including a plurality of carry-down cams on a rotatable carry-down cam shaft having a fixed location relative to the framework and a carry-down roller assembly including a plurality of carry-down rollers on a rotatable carry-down roller shaft having a movable location relative to the framework. The carry-down rollers are opposed to and spaced from the carry-down cams, providing a nip having a nip distance therebetween. At least one biasing element biases the carry-down roller shaft toward the nip. The inserts are moved through the nip individually. A thickness tuning adjustment assembly moves the carry-down roller assembly to adjust the nip distance. A vacuum assembly is in communication with a movable sucker assembly that has sucker ports being movable toward and away from the nip.

An apparatus to select-introduce blank sheets and/or printed materials and corresponding method, comprising a positioning seating, a selector unit and an introduction unit suitable to select and introduce sheets in sequence according to the format and basic weight, maintaining high cadences and at the same time reducing the causes of blockages of the sheets in the apparatus.
