<p>Pharmaceutical hard-shell cellulose capsules, each capsule consisting of a capsule body and a capsule cap, are made from an aqueous solution of a thermogelling cellulose ether composition in a capsule machine using pins (22) as molds. Solution is gelatinized and dried on the surface of a pin (22) to form a cellulose capsule part (28). Adhesion between the cellulose capsule part (28) and the pin (22) is broken by using a gripper (24) and applying a grip of predefined force and a frictional force on a selected sacrificial portion of the outer circumferential surface of the capsule part (28), the frictional force aligned with the pin axis. After breaking adhesion, gripping is released and the part (28) is moved off the pin (22).</p> |
