Japanese Patent JP2018188156
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an envelope paper which enables prevention of wrinkles on an enclosed content.SOLUTION: The envelope paper P2 is made up of a first paper part 109 and a second paper part 113 which extends, via a bending line P2a, from the first paper part 109 toward the envelope extensive direction. An enclosing and sealing device 5 transfers a content B, being partially nipped toward the rotary axis direction by transfer rollers 72, inserts it between the first paper part 109 and the second paper part 113 and folds the envelope paper P2 at the bending line while nipping the content B with a predetermined pressure by the envelop-folding rollers, thereby enclosing the content B. In order for the content B to slide smoothly into the envelope when the content B is partially nipped by the envelop-folding rollers and transferred by the transfer roller 72, a sliding part 113 coated with a slipping agent is formed inside the first paper part 109 and the second paper part 113 along the bending line P2a.SELECTED DRAWING: Figure 3
