摘要:
Relieved pattern of a resin original pattern plate, which does not exhibit fluidity at transferring temperature and possesses elastic modulus no smaller than 10 kg/cm.sup.2, preferably no smaller than 100 kg/cm.sup.2, is transferred onto thermoplastic resin material having fluidity at the transferring temperature (ASTM D1238, load 21.6 kg) of at least 0.01 dg/min, preferably at least 0.1 dg/min, by pressing the thermoplastic resin material to the original pattern plate under a pressure condition where elastic deformation of the original pattern plate is kept within 10%. The resin original pattern plate is prepared by controlling the photo-polymerizable resin composition to adjust its crosslink-ability and then photo-polymerizing, whereby the resulting resin original pattern plate possesses an elastic modulus of 10 kg/cm.sup.2 or higher at transferring temperature. The photo-polymerizable resin composition includes, as its major ingredients, either polymer, polyfunctional monomer (10-90% by weight, preferably 30-70% by weight, and having viscosity of at least 10.sup.3 poise at transferring temperature), photo-sensitizer and thermal polymerization inhibitor, or cross-linkable polymer (having at least 1000 molecular weight and double bonds at least one for each 1000 molecular weight), monomer (5-50% by weight, preferably 10-40% by weight), photosensitizer and thermal polymerization inhibitor.

摘要:
A printing resin plate is produced by adoption of such process and apparatus that a negative film is placed on a transparent plate positioned on a frame stand; a liquid photopolymerizable resin is applied through a cover film onto said negative film to form a layer; the frame stand and/or a means having a belt, which has been extended between at least two rolls and which can rotate synchronously with the frame stand, are moved to insert a support into a space between the liquid photopolymerizable resin layer on the frame stand and the lower surface of said belt; the frame stand is moved to below the lower surface of the belt while pressing the support with the lower surface of the belt by the downward pressure of the belt thereby closely adhering the support onto the liquid photopolymerizable resin layer; and then the liquid photopolymerizable resin layer is exposed to light.
摘要:
The invention provides a sewing machine with uncurling device comprising a separating plate and a suction tube, the separating plate is placed in front of the needle drop point and it separates upper and lower fabrics fed to a needle drop point with their respective edge hems overlapped, and the suction tube has an air-intake with its size covering across upper and lower surfaces of the separating plate and it straightens curls at separated edge hems of the both fabrics by air flow sucked into the suction tube through the air-intake. As the overlapped edge hems of the both fabrics are fed into the needle drop point, the curls at the edge hems are reliably straightened regardless of the shape thereof. Therefore, it eliminates troublesome manual labor for straightening the curls before feeding of the fabrics.
摘要:
A sewing machine with a dust removing device prevents trouble such as faulty sewing caused when dust including waste thread and waste cloth is collected under a throat plate, in performing, for example, interlock stitch sewing by an overlock sewing machine. Specifically, an upward air introducing path is provided, through which the cooling airflow generated by a cooling fan actuated during sewing operation is fed to an air introducing path for oil cooling underneath a lubricating oil storage part, and, through which the cooling airflow passing through the air introducing path for oil cooling is blown up from the underside of a frame to a needle location of the throat plate, in order to blow up the dust. An opening of one end of a suction pipe for collecting dust attached to the frame is disposed sidewise above the throat plate. The self-cleaning action obtained by effectively utilizing the airflow from the cooling fan for cooling lubricating oil, enables to prevent trouble such as faulty sewing due to the collected dust, and prevent dust from widely scattering around the upside of the throat plate, thereby to maintain working environment hygienic.
