摘要： A process for producing an aliphatic polyester includes the steps of: heating a cyclic ester at a melting point or higher to transform the cyclic ester into molten state and convert a moisture contained in the cyclic ester into free carboxylic acid; measuring an amount of the free carboxylic acid in the molten cyclic ester; feeding a proton-source compound in an amount determined based on the measured amount of the free carboxylic acid into the molten cyclic ester; and subjecting the cyclic ester to ring-opening polymerization. The process provides an aliphatic polyester with a desired molecular weight which can be set easily and accurately. An apparatus for the process is also provided.

摘要： Polyglycolic acid and polylactic acid having a weight-average molecular weight of at most 50,000 are melt-kneaded in the presence of a thermal stabilizer to obtain a polyglycolic acid-based aliphatic polyester composition. The aliphatic polyester composition alleviates the too fast crystallizability of polyglycolic acid which has been problematic in forming or molding of polyglycolic acid alone or in combination with another thermoplastic resin, thus showing a crystallization speed which has been lowered and can be controlled in a wide range.

摘要： A process for producing an aliphatic polyester, comprising: subjecting at least two serial stages of bulk-phase ring-opening polymerization and a solid-phase polymerization step, wherein a cyclic ester held in a dry air atmosphere is supplied to a first reactor to perform a first stage polymerization, thereby obtaining a partially polymerized molten product, and the resultant partially polymerized molten product is supplied to a second reactor held under a dry inert gas atmosphere to perform a second stage polymerization. As a result, the production efficiency can be improved, while maintaining excellent properties of the aliphatic polyester product.

摘要： A sheet folding system includes a plurality of sheet folding apparatuses configured to receive and perform a folding process on a sheet and circuitry configured to distribute sheets to the plurality of sheet folding apparatuses. Each of the plurality of sheet folding apparatuses includes a folding device configured to fold the sheet, a first conveyance passage configured to convey the sheet downstream in a sheet conveyance direction without passing through the folding device, a second conveyance passage configured to convey the sheet to the folding device, a third conveyance passage configured to convey the sheet from the folding device downstream in the sheet conveyance direction, and a junction between the first conveyance passage and the third conveyance passage. The circuitry controls sheet conveyance to prevent an interference, at the junction, between the sheet conveyed from the first conveyance passage and the sheet conveyed from the third conveyance passage.

摘要： A sheet folding apparatus includes a conveyance member to convey a sheet from an ejection member at a first speed lower than a conveyance speed by the ejection member or a second speed substantially same as or higher than the conveyance speed; a registration member; a pair of first and second rollers to rotate in forward and reverse directions; a plurality of folding rollers downstream from the second roller, to rotate in forward and reverse directions to fold the sheet; and circuitry to determine whether the sheet is equal to or smaller than a reference length from an exit position from the ejection member to a folding start position downstream from the pair of the first and second rollers. The circuitry performs first-speed folding when the sheet is equal to or smaller than the reference length and performs second-speed folding when the sheet is longer than the reference length.

摘要： A sheet processing device includes a conveying unit, a presser, an end detector, and a setting unit. The conveying unit conveys a sheet having a crease formed therein. The presser presses the crease in the sheet. The end detector detects an end in a conveying direction of the sheet at a position upstream of the presser in the conveying direction. The setting unit sets a crease position where the crease is to be formed. Upon detection of the end in the conveying direction, the conveying unit conveys the sheet to a position where the crease faces the presser, on the basis of the crease position set by the setting unit. The presser presses the crease in the conveyed sheet.

摘要： A sheet processing apparatus includes: a second conveying roller pair that receives and conveys a sheet conveyed by a first conveying roller pair; a first folding roller pair that forms a first fold on the sheet; and a first rotation unit capable of rotating the second conveying roller pair and the first folding roller pair. One roller of the second conveying roller pair and one roller of the first folding roller pair are a common roller shared therebetween. The second conveying roller pair causes the sheet to be deflected and guided to the first folding roller pair, and the first folding roller pair forms the first fold on the deflected sheet by rotating the first rotation unit in a certain direction in a state in which the sheet is held by the first conveying roller pair and the second conveying roller pair.
