A squeezing roller granulator that has a squeezing roller pair composed of a toothed pressure roller and a toothed squeezing roller. The teeth of the pressure roller and the squeezing roller have tooth flanks that are situated between a tooth root region and a tooth tip region. The tooth root region has an outer diameter that is smaller than the outer diameter of the tooth tip region, and the tooth tip region of at least one of the rollers of the squeezing roller pair has three squeezing zones including a middle squeezing zone, which define different distances between the tooth tip regions with a minimum distance in the region of the middle squeezing zone, and the contour of the tooth flanks and the tooth root region of the rollers of the squeezing roller pair defines a maximum cross-section of granulate cushions to be formed.

A squeeze roller granulator that has a cylindrical pressure roller and a toothed squeeze roller. The gearing of the squeeze roller has tooth flanks that are situated between a tooth root region and a tooth tip region. The tooth root region has an outer diameter that is smaller than the outer diameter of the tooth tip region. The tooth tip region of the squeeze roller has three crushing zones including a middle crushing zone, which define different distances from the cylindrical pressure roller with a minimum distance in the region of the middle crushing zone, and the contour of the tooth flanks and the tooth root region of the crush roller in cooperation with the contour of the cylindrical pressure roller defines a maximum cross-section of granulate cushions to be formed.

The present invention provides novel biolatex conjugate compositions and methods of production and use thereof. The novel biolatex conjugate compositions comprise a biopolymer-additive complex (prepared by co-extruding a biopolymer feedstock, at least one performance-enhancing additive, and at least one plasticizer under shear forces) reacted with a crosslinking agent under shear forces. The biolatex conjugate compositions exhibit enhanced performance properties for coated paper, paperboard, and other applications using extremely low levels of performance-enhancing additives.

摘要:
A method for manufacturing elastomeric material components of a tyre for a vehicle wheel includes feeding a continuous elongated element from a delivery member for application onto a support, giving the support a rotary motion around a geometrical rotation axis of the support, so that the elongated element is circumferentially distributed on the support, and carrying out controlled relative displacements for transverse distribution between the support and the delivery member to form the elastomeric material components of the tyre with the elongated element. Feeding the elongated element takes place by extrusion of elastomeric material through at least one extrusion screw and at least one gear pump. The component is defined by a plurality of coils laid down in a pre-established deposition pattern depending on a cross-section outline to be given to the component. An apparatus for manufacturing elastomeric material components of a tyre for a vehicle wheel is also disclosed.

A caterpillar take-off device for hauling off extrusion products, in particular plastic tubes, includes at least two caterpillar tracks arranged symmetrically in relation to a length axis of the caterpillar take-off device, at least during take-off process by changing the distance from the caterpillar tracks to the length axis. In the event of a change in cross-section of the extrusion product, the change is measured and the distance of the caterpillar tracks from the length axis is automatically adjusted such that the symmetry axis of the extrusion product coincides with the longitudinal axis of the caterpillar take-off unit.
摘要:
Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track. The extrudate handling system provides greater accuracy, reduced costs, and improved results.
