A Press element and a method for manufacturing a structured press element, wherein a heterogeneous mask is applied on a metallic base element, after which a surface treatment is carried out and the heterogeneous mask has a certain resistance to the surface treatment.

The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.

The invention relates to a press roller for a roller press, in particular for briquetting, compacting or grinding granular material, having a roller core (1) and a roller sleeve fastened to the exterior of the roller core (1), said sleeve being composed of a plurality of segments (2), distributed over the circumference, with mutually facing lateral faces (3). The segments (2) have clamping shoulders (5) which extend around the front faces and have first clamping surfaces (8). The segments (2) are releasably fastened at each front face to the roller core (1) by means of at least one fastening ring (6), said fastening ring fitting over the clamping shoulders (5) of the segments (2). The front faces (12) and/or clamping shoulders (5) of the segments (2), in the front face edge regions associated with the lateral faces (3), have outer material reinforcements (13) which protrude outwardly relative to the first clamping surface (8) in the radial direction and/or relative to the front face (12) in the axial direction and define, together with the clamping surfaces (8), pocket-type recesses (14) in between them in the circumferential direction, second clamping surfaces (9) of the fastening ring (6) resting against said pocket-type recesses.

A device for compression of emptied containers, the device for compression of emptied containers including a container compressing arrangement provided with a first and a second roller, each roller having annular segments provided with specially shaped protruding elements. The device is for compression of plastic bottles as well as metal cans.

An installation for forming a fiber preform, includes a follower roller. The follower roller presents a profile in section that has at least a first slope forming an angle with the axis of the follower roller and a second slope forming a second angle with the axis of the follower roller that is different from the first angle. The installation also has at least one backing roller presenting a shape complementary to the first and second slopes, the installation including a holder for holding each backing roller and configured to hold the backing roller at a predetermined distance from the first and second slopes or configured to apply contact pressure from the backing roller against the first and second slopes.

An apparatus includes a first roll and a second roll on each of which a pattern is formed, a first motor and a second motor to rotate the respective rolls, a shaft direction supporting mechanism to support the second roll along a shaft direction and an axial position adjusting mechanism configured to move the shaft direction supporting mechanism along the shaft direction. The posture of the rotating shaft of the second motor is maintained constant at all times, and the second roll is moved in the shaft direction along the first roll, thereby adjusting the positions of both patterns on the first roll and the second roll along the shaft direction.
