The invention relates to a device for hydroentangling and/or structuring webs that includes an suctioning rotating drum and a structured shell, including at least two rings which can be pushed on and attached to the drum, is disposed at a distance from the cylindrical surface of the drum around. A web can be at least partially looped around the structured shell. At least one water bar including a nozzle strip with a plurality of nozzles is arranged relative to the structured shell to entangle and/or to structure and/or to perforate the web by the water jets. The invention further relates to the structured shell.

The present invention relates to an applicator apparatus for dyeing and finishing in which diagonal application grooves are formed in a longitudinal direction in an outer circumferential surface of a roller used to apply a chemical and reverse diagonal application grooves are formed to intersect the formed diagonal application grooves to allow the chemical to be evenly discharged to an outer circumferential surface of a pickup roller so that fabric dyeing efficiency is increased. The applicator apparatus for dyeing and finishing includes a storage tank (100) in which a chemical is accommodated, a guide roller (200) configured to guide a fabric (f) to be conveyed, a first pickup roller (300) which is installed at an upper portion of one side of the storage tank (100) and has an outer circumferential surface coming in contact with a surface of the fabric (f) being conveyed along the guide roller (200) and a lower portion dipped in the chemical accommodated in the storage tank (100) so that the chemical is attached to the outer circumferential surface and conveyed due to forward rotation of the first pickup roller (300), and an application roller (400) which is installed at an upper side of the first pickup roller (300), rotates in a reverse direction, and has diagonal application grooves (410) formed along an outer circumferential surface and reverse diagonal application grooves (420) formed to intersect the formed diagonal application grooves (410) so that the chemical conveyed along the first pickup roller (300) enters and passes through the formed diagonal application grooves (410) and reverse diagonal application grooves (420) and is guided to be evenly discharged to the outer circumferential surface of the first pickup roller (300) and applied to the fabric (f).

A drum to be used in textile finishing operations has a body and a helical wrap surrounding the body from the middle part to the ends thereof. The drum has a plurality of bars arranged at certain intervals determined according to the requirements of the process.

A segment roller (1) has a roller body (2), which is mounted rotatably about an axis (3). To this end, the roller body (2) has on the outside grooves (9), in which tongues (8) of profiles (7) engage. These profiles (7) grip the material web (5) directly or indirectly. In order to increase the working life and improve the mechanical properties of the profiles (7), the profiles (7) are of shear-resistant configuration and have elastic lips (20). These elastic lips (20) are deformed upon the engagement of the tongue (8) in the groove (9).

A curl straightening method applied upon printing on a spread medium in a printing step, the method being provided with a first spreading step of spreading the medium fed out from a medium roll between a feeding step of feeding the medium from the medium roll in which the medium made of a textile fabric and having a predetermined width is wound on a roll core, and the printing step of printing on the medium fed out from the medium roll, and in the first spreading step, spreading of the medium is performed in a state where the medium fed out from the medium roll is stretched on an outer circumference of a first spreader roller rotating about a pivotal axis parallel to a pivotal axis of the medium roll, and the medium has its surface side with a curl stretched on the outer circumference of the first spreader roller.

A method of producing sizing agent-applied carbon fiber bundles includes a sizing agent application process of immersing a plurality of carbon fiber bundles running side by side in a sizing agent bath, followed by a dry process performed to obtain sizing agent-applied carbon fiber bundles and, to address issues of wrapping of a carbon fiber bundle caused by sticking of a sizing agent solution to a guide roller, the first guide roller for the carbon fiber bundles after being immersed in the sizing agent bath and coming out of a liquid surface of the sizing agent bath is set to have a surface adhesive force of 0.2 N/cm.sup.2 or less.
