Three-dimensional printing system and equipment assembly
A three-dimensional printing system and equipment assembly for the manufacture of three-dimensionally printed articles is provided. The equipment assembly includes a three-dimensional printing build system, an optional liquid removal system and an optional harvester system. The build system includes a conveyor, plural build modules and at least one build station having a powder-layering system and a printing system. The equipment assembly can be used to manufacture pharmaceutical, medical, and non-pharmaceutical/non-medical objects. It can be used to prepare single or multiple articles.
Method and apparatus for assembling absorbent articles
The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.
Process for producing laminated foam sheet and extruded laminated foam sheet
A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.
Manufacturing method and manufacturing apparatus for laminate
A manufacturing method including a first conveying step of conveying the sheet in a lateral or oblique lateral direction along a sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the sheet on the sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the sheet and the film raw material after the tip part overlaps the sheet on the sheet pass line, the second conveying step conveying the sheet and the film raw material in a mutually overlapping state along the sheet pass line; and an introducing step of introducing the sheet and the film raw material in the mutually overlapping state to the joining part from the sheet pass line.
Impact forming of thermoplastic composites
Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. A peening system with multiple pins provides compaction over irregular surfaces, providing superior performance as compared with traditional compaction rollers. The apparatus that carries out the techniques include a tape dispensing system, a heating system, a peening system, a processor and a memory coupled to the processor. The memory contains instructions that when executed by the processor perform the steps of: dispensing a first ply of thermoplastic composite tape over a mandrel; dispensing a second ply of thermoplastic composite tape on the first ply; and peening the second ply onto the first ply, such that the second ply is bonded to the first ply.
MULTILAYER CONTAINER, METHOD FOR MANUFACTURING SAME, AND METHOD FOR MANUFACTURING RECLAIMED POLYESTER
Provided is a multilayer container including a polyester layer containing a polyester resin (X), and a polyamide layer containing a polyamide resin (Y), a yellowing inhibitor (A), and an oxidation accelerator (B). The content of the polyamide resin (Y) is from 0.05 to 7.0 mass% relative to the total amount of all polyamide layers and all polyester layers. The yellowing inhibitor (A) is a dye, and the content of the yellowing inhibitor (A) is from 1 to 30 ppm relative to the total amount of all polyamide layers and all polyester layers.
ARTICLES, DIES AND METHODS OF MAKING THE SAME
Articles (100, 200, 300) comprising first (101, 201, 301) and second layers (102, 202, 302) each having first and second opposed major surfaces and between the first and second layers a series of first walls (110, 210, 310) having aspect ratios between 1.5 and 5 providing a series of microchannels, and methods for making the same. Embodiment of coextruded articles described herein are useful, for example, in cushioning applications where high levels of compression are desired.
METHODS, SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR PRODUCING RIGID FOAM BOARDS USING OPTICAL AND INFRARED IMAGING
Disclosed are methods, systems and computer program products for producing rigid foam board, comprising: depositing a foam producing mixture on a facer as it travels along a conveyor; producing a rigid foam board via an exothermic reaction; imaging the rigid foam board after it is produced but before it has cooled to room temperature, using an infrared or an optical imaging device, to capture an image of the rigid foam board; receiving a signal comprising the captured image from the imaging device to a computing device; determining, based on the captured image, if a defect that requires correction exists in the rigid foam board; and optionally, in response to determining that a defect requiring correction exists, modifying a process parameter in producing rigid foam board.
Synthetic leather for steering wheel cover having improved durability and method for preparing the same
The present invention relates to a synthetic leather for a steering wheel cover of a vehicle, and a method for preparing the same. The synthetic leather including a fiber base layer (101) including a microfiber nonwoven fabric, an urethane porous layer (102) formed on the fiber base layer, a polyurethane resin skin layer (104) formed on the urethane porous layer, and prepared by polymerizing an isocyanate compound and a polyol compound including polycarbonate-based polyol, fluorine-based polyol and ester-based polyol, and an adhesive layer (103) for adhering the urethane porous layer and the skin layer.
Method of making coextruded, cross-linked polyolefin foam with TPU cap layers
The present disclosure is directed to a physically crosslinked, closed cell continuous multilayer foam structure comprising at least one foam polypropylene/polyethylene layer with a TPU cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer with at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.
