Abstract: A corrugated paperboard box making machine, which includes: a slotter for slotting a corrugated paperboard sheet to form slots; a die-cutter disposed downstream of the slotter, the die-cutter including a die cylinder with a punching die and an anvil cylinder; a cutting blade for cutting, in cooperation with the anvil cylinder, the corrugated paperboard sheet slotted by the slotter, into two small-size corrugated paperboard sheets, along a direction perpendicular to the conveyance direction; and a displacement mechanism for displacing the cutting blade as to allow the cutting blade to be selectively set in a cutting position and a non-cutting position.

Abstract: Disclosed is a corrugated paperboard box making machine, which comprises: a slotter for slotting a corrugated paperboard sheet to form slots, a die-cutter disposed downstream of the slotter, the die-cutter including a die cylinder with a punching die and an anvil cylinder; a cutting blade for cutting, in cooperation with the anvil cylinder, the corrugated paperboard sheet slotted by the slotter, into two small-size corrugated paperboard sheets, along a direction perpendicular to the conveyance direction; and a lifting and lowering mechanism for lifting and lowering the cutting blade in such a manner as to allow a position of the cutting blade with respect to a corrugated paperboard sheet being passing through the anvil cylinder to be changed between a cutting position where the cutting blade is permitted to cut the corrugated paperboard sheet, and a non-cutting position where the cutting blade is precluded from cutting the corrugated paperboard sheet.

Abstract: Fine polyurethane particles or fine polyurethane gel particles, which have been surface-covered with colloidal polyurea particles, are provided. They are produced by emulsion polymerization of a polyisocyanate compound and an active-hydrogen-containing compound in an inert liquid while using colloidal polyurea particles as an emulsifier.

Abstract: A textile finishing composition comprises a water dispersible urethane prepolymer and a water soluble methylol compound, a glyoxalamide adduct, or bis(.beta.-hydroxyethyl) sulfone.
