CONTINUOUS FLOW DRYER FOR TREATING BULK MATERIAL
20180003439 · 2018-01-04 ·

A continuous flow dryer system according to various embodiments can include a source for supplying a material to be treated having a high moisture content, such as a distiller wet grain, a profile screw compression dryer, a profile screw, and a drive coupled to the profile screw for axially rotating the profile screw. The profile screw compression dryer includes an inlet for receiving the material for drying, which is fed therein in a controlled manner. The profile screw is provided within the housing of the dryer. The profile screw has a diameter that increases in dimension in a direction away from the inlet for increasing the compressive force applied to the material to assist with drying as the profile screw rotates and moves the material longitudinally along the profile screw to produce a final product, for example, a distiller dried grain for use as an animal feed.

Methods and machines for making oral products

A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

METHOD AND DEVICE FOR PRODUCING A DECORATIVE WALL- OR FLOOR PANEL
20230018307 · 2023-01-19 ·

The present disclosure relates to a method for producing a decorative wall- or floor panel, having the method steps: • a) providing a melted polymer mass; • b) extruding the molten polymer mass through a nozzle; • c) finish-sizing the molten polymer mass to form a panel-like carrier material by means of an assembly of multiple rotatable rolls, wherein the individual rolls are disposed one above the other or one behind the other and each individual roll forms at least one finish-sizing nip with neighbouring rolls, through which nip the melted polymer mass is passed, and wherein the finishing nip heights can be variably adjusted by a horizontal and/or vertical movement of individual rolls during the production process; • d) applying a decor pattern that imitates a decor template to at least one sub-region of the at least partly finish-sized carrier material, and • e) applying a protective coating to at least one sub-region of the decor.

DIRECT PRINTING ONTO EXTRUDED PVC SLATS
20230211621 · 2023-07-06 · ·

Described is a process and system for direct printing of a decorative pattern onto an extruded PVC slat. The process includes providing a hot extruded PVC slat; directly contacting a surface of the hot extruded PVC slat with a direct printing cylinder as the slat is moved in a downstream direction, where the cylinder has a pattern with a cell structure that receives ink and rotates to directly apply the ink in the form of the pattern onto the surface of the hot extruded PVC slat. The process also includes controlling a temperature of the direct printing cylinder to inhibit drying of the ink while present on the direct printing cylinder.

Method and apparatus for forming uncured rubber component

A method for forming an uncured rubber component, the method includes conveying an uncured extruded rubber strip extruded continuously from an extruder using a conveyor, the conveyor including a first conveyor and a second conveyor located at a downstream side of the first conveyor in a convey direction, the step of conveying including shrinking the uncured extruded rubber strip, wherein the step of shrinking is such that the uncured extruded rubber strip, in a relaxed state of a U-shaped manner, passes through fluid held in a tank between the first conveyor and the second conveyor without being restrained so that the uncured extruded rubber strip shrinks freely while receiving buoyancy from the fluid, and cutting the uncured extruded rubber strip in a predetermined length to form an uncured rubber component, after the step of shrinking.

Method for forming a stress-free multilayer PVC sheet material
11691404 · 2023-07-04 · ·

A method for forming a multilayer plastic sheet material (1) for floor and/or wall panels, wherein a first polymer mass comprising a rigid PVC is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is passed to two or more rolls of a finishing stand, which processes the multilayer plastic strand into a sheet of defined thickness, which is then led away via a transport device to a sawing device to be cut to the desired length, wherein, after the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand, wherein the speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that said plastic strand is processed without stress.

System and method for reducing draw resonance in plants for the production of plastic film
11491698 · 2022-11-08 ·

A system and method for reducing draw resonance of a plastic material in molten state, so-called melt, leaving an extrusion group of a plant for the production of plastic film, includes at least one thermostatically-controlled cylinder, having an embracement angle of the melt on the cylinder that is adjustable on the basis of the process rate, i.e., the linear movement speed of the plastic film, and/or on the basis of the temperature measured in the proximity of or in correspondence with the clamping area of the melt in a thermoforming, calibration and cooling group included in the plant and positioned downstream of the system.
