A METHOD FOR PRODUCING CELLULOSE PRODUCTS AND A ROTARY FORMING MOULD SYSTEM
20220355516 · 2022-11-10 ·

A method for forming cellulose products from an air-formed cellulose blank having a base and one or more forming moulds attached to the base which is arranged to rotate around a rotational axis, wherein each forming mould comprises a first mould part Wand a corresponding second mould part wherein during rotational movement of the base around the rotational axis each first mould part is arranged to engage with its corresponding second mould part in a pressing direction. The method comprises arranging the cellulose blank in a position between a first mould and the second mould forming the cellulose products in the rotary forming mould system, by applying a forming pressure between the first mould and its corresponding second mould through an engaging movement of the first mould in relation to its corresponding second mould in the pressing direction, wherein the forming moulds are rotating with the base around the rotational axis.

11235494 · 2022-02-01 · ·

A seal member formed in a line shape having ends is inserted in a seal groove formed on at least one of adjacent side surfaces of segments. A lip portion is provided on a seal upper portion of the member so at least a tip end thereof projects to an outside of the seal groove when the member is inserted in the groove. The seal member is hollow or includes a concave portion on at least a seal bottom portion thereof. When assembling the segments as a single structure, the adjacent side surfaces of the segments are coupled to each other, and the seal member is crushed in a cross sectional direction by the side surface of the other segment to seal between the segments. With this, complication of manufacturing steps can be suppressed or avoided while realizing a satisfactory sealed state between the adjacent segments of a mold.

INSULATING COATING DEVICE FOR ELECTRIC WIRE

Provided is an insulating coating device for an electric wire, including a pressing pipe. The pressing pipe includes two first pressing parts which are configured to divide the pressing pipe into two parts along a longitudinal cross section of the pressing pipe, an inner wall of the pressing pipe is provided with an air bag, and the air bag is provided with an air pipe joint which penetrates to an outside of the pressing pipe. In the insulating coating device for the electric wire, a self-curing insulating material is coated on joints of the electric wires, the air bag is used to squeeze the self-curing insulating material such that the self-curing insulating material is shaped and compacted, so that cavities generated in a coating process is reduced, and the self-curing insulating material is uniformly attached to the joints of the electric wires.
