Abstract
A pocket roll centered on and rotatable about a respective axis has an outer surface formed with an array of open pockets separated by directed lands. The pocket-roll outer surface has a predetermined coefficient of friction. A blister foil is fed to the pocket roll with blisters of the blister foil fitting in the pockets. A seal roll rotatable about a respective axis adjacent the pocket roll has an outer surface pressing a cover foil against the blister foil so that the foils are pinched between the rolls. Slip inserts set in at least some of the lands, extend axially of the pocket-roll axis and form in the respective lands axially extending outer-surface regions having coefficients of friction smaller than the coefficient of friction of the pocket-roll outer surface. A position-correcting unit has a sensor and detects and adjusts the positions of the blisters relative to the direction.
