<p>The invention relates to a vacuum holding device comprising a cylinder (3) with an outer shell (7, 9, 14, 15) with air channels (6), which control the vacuum by means of a valve (11, 12, 13), so that passage and holding force are established only when an object (1) is in contact with the cylinder (3). This reduces the consumption of vacuum.</p> |
