Title:
結合された細断繊維で不織ウェブを形成するための細断繊維のストランドの収集及び堆積
Document Type and Number:
Japanese Patent JP4065325
Kind Code:
B2
Abstract:
An air cannon (100), formed by associating an inlet cone (116), an air amplifier (104) and an outlet cone (124) with one another, receives chopped fibers and forcefully deposits the chopped fibers on a collection surface (102) or web moving beyond an outlet end (126) of the outlet cone (124). A binder is applied to the resulting mat (172) of chopped fibers, the binder is activated by the application of energy with the resulting treated mat (182) being compacted, cooled and rolled up to form a chopped strand mat package (194). For wide mats, one or more banks (130) of air cannons (100) extend across the moving collection web. The air cannons (100) of each bank (130) are alternately directed up-line and down-line of the web to reduce interference between the air cannons (100) by means of L-shaped support rods (136) which have generally horizontal and generally vertical legs (136H, 136V) which are separated from one another by acute and obtuse angles (140, 142) for up-line and down-line direction, respectively. The air cannons (100) can also be individually adjusted to vary the aimed direction of the air cannons (100) across the web by rotation of the generally horizontal legs (136H) of the L-shaped support rods (136). The air cannons (100) forcefully direct chopped fibers to the web to overcome air turbulence within a forming hood (170) and forces due to static electricity.
