PROBLEM TO BE SOLVED: To appropriately adjust heating conditions in response to a conveyance speed of a nonwoven fabric in a bulkiness recovery apparatus for a nonwoven fabric.SOLUTION: There is provided an apparatus for recovering bulkiness of a nonwoven fabric by blowing hot air to the nonwoven fabric that is conveyed in a conveyance direction to heat. The apparatus includes: a conveyance unit for conveying the nonwoven fabric a heating unit that includes a case member through which the conveyed nonwoven fabric enters and exits and a jetting port for jetting the hot air into a space inside the case member and is for blowing the hot air from the jetting port to a surface of the nonwoven fabric that is conveyed in the space inside the case member to heat and a control unit for controlling a conveyance speed of the nonwoven fabric that is conveyed by the conveyance unit and changing conditions when the nonwoven fabric is heated according to the conveyance speed of the nonwoven fabric.COPYRIGHT: (C)2015,JPO&INPIT【課題】不織布の嵩回復装置において、不織布の搬送速度に応じて加熱条件を適当に調整する。【解決手段】搬送方向に搬送される不織布に熱風を吹き付けて加熱することにより前記不織布の嵩を回復する装置であって、前記不織布を搬送する搬送部と、搬送される前記不織布が出入りするケース部材及び前記ケース部材の内部の空間に前記熱風を噴射する噴射口を具備し、前記ケース部材の内部の空間内において搬送される前記不織布の表面に前記噴射口から前記熱風を吹き付けて加熱する加熱部と、前記搬送部によって搬送される前記不織布の搬送速度を制御するとともに、前記不織布を加熱する際の条件を前記不織布の搬送速度に応じて変更する制御部と、を備える。【選択図】図2
