An apparatus for a thermal treatment of a textile web includes at least one drum with a perforated casing surface around which a material web can be at least partially wrapped, at least one connecting element, and a patterning shell with a plurality of openings separated by ridges fitted onto the casing of the drum. The patterning shell includes at least two segments detachably connected with aid of the at least one connecting element. The at least one connecting element is arranged on or integrated into a ridge.

A system for drying a container includes an air manifold having a plurality of outlets to deliver pressurized air toward passing containers. A surface, such as a conveyer belt, supports one or more such containers. A frame including a track or rollers is arranged at a predetermined distance from the surface, the frame being configured to brace the one or more containers against forces acting on the one or more containers from the pressurized air.

The invention relates to an apparatus (10) and a method for handling articles (11). The apparatus (10) comprises a gripping device (14) with a suction surface (16) that can be subjected to negative pressure for grasping the articles (11) by suction. The suction surface (16) is covered with a layer (24) that is elastically deformable and air-permeable, at least in certain regions.

The apparatus (10) is also equipped with a drying device (32), which drying device can interact with the layer (24) that is attached to the suction surface (16) or forms the suction surface (16), in order to remove moisture that is bound or adhering therein.

Disclosed is a sound-absorbing material, a method, and a speaker, a sound-absorbing slurry is frozen by using a freezing conveyor belt, and the sound-absorbing slurry is then molded by a mold or coated onto a film. During pre-cooling of the sound-absorbing slurry in a first freezing zone of the conveyor belt, temperatures of the mold and a carrier film are reduced, followed by rapid freezing in a second freezing zone. Pre-cooling the mold in advance ensures uniform freezing of the sound-absorbing slurry. The freezing time of the material may be controlled by adjusting the speed of the conveyor belt. A temperature gradient is formed between the freezing conveyor belt and hot air thereabove. This enhances the top-bottom permeability of the sound-absorbing material, and thus improves the performance of the sound-absorbing material. The preparation efficiency of sound-absorbing material is increased, thereby facilitating scalable mass production is facilitated.

A dielectric drying method for ceramic formed bodies includes drying a plurality of ceramic formed bodies placed side by side in an arrangement direction Y perpendicular to a conveying direction X on an upper surface of a drying table by conveying the ceramic formed bodies between electrodes of an upper electrode and a lower electrode, and applying a high frequency between the electrodes. The upper electrode includes: a central region; and two end regions between which the central region is located, in the arrangement direction Y. The central region has a flat surface portion parallel to an upper end surface of the ceramic formed body. Each of the two end regions has an inclined portion inclined toward the lower electrode side.
