Abstract

Bottles are closed with capsules whose free end segment is crimped over the top of the bottles. To avoid abrasion and turbulence, the end segment of the cap is deformed by a simultaneous, uniform upsetting of its entire circumference in a female die. An apparatus for carrying out the invention has a female die that is split into two parts, with cylindrical bores and with a constricting rib on a bottom portion which fits around the neck of the bottles. The rib has a concavely rounded side upon which the end segment of the cap, is thrust against and is deflected toward the bottle. The female die is split into two jaws that can be pivoted toward one another and whose opening and closing motion is coupled to the motion of an axially displacable male dies that displace the capsules in the female die for sealing the capsules onto the bottle.
