A guided endless, revolvingly driven traction element is equipped with controlled gripper units or grippers arranged in spaced relationship from each other. These gripper units are adapted to grip one margin of the paper products which constitutes a lateral marginal edge of the product as seen in the transport direction thereof. The gripper units have substantially planar clamping faces inclined a...

When isomerizing part of the glucose content of a glucose-containing solution to fructose, the productivity of glucose isomerase immobilized on an SiO2 carrier is increased considerably by pre-contacting the glucose-containing solution with particles of SiO2 or aluminum silicate. An apparatus is used having a reaction vessel containing the immobilized glucose isomerase and a pre-column containing...
