margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　布铗的工作原理如图5-28（a）所示。在布铗链的进布端，由于布铗链轮上方的开铗转盘的作用，将绕经转盘的有柄布铗打开，使织物的边部进入其间。在布铗离开转盘时，由于滑轮（图5-25）被织物边部托住，不能落入底板的轮槽中，刀口并未夹住织物。待布铗沿该段轨道的开档逐渐加大而使织物边缘外移至一定位置时，滑轮落至底板轮槽中，刀口触及织物边部，并将它夹住，从而使铗持宽度均匀。出布端织物脱铗时，也是采用同样方法，打开铗舌。无柄布铗则是采用酚醛层压板制的开铗板来打开铗舌的，见图5-28（b）。</span></p><p style="text-align: center;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　为了防止织物在运转中脱铗、拉破、夹毛，铗舌动作必须灵活可靠，刀口与铗座底板接触面必须平齐无缝，刀口外侧两段必须全幅接触，每10mm不得少于两点。可用0.05mm厚的纸片试夹，拉动两纸角，不得有脱铗、夹毛、夹碎等现象。圆柱销两端向外翻口铆紧后应无松动，不得有开裂现象。铗座底板四周均需倒圆角。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　针铗的结构如图5-29所示。针板是针铗中的主要元件，在黄铜针板上，植有稍呈外倾（约8°）间隔相等的长针（尖针）与短针（圆柱针）。织物边部进入针铗时，用两只大小毛刷轮将织物边部压入针板，刺住织物。针的表面应光滑，针尖锋利不能有毛刺，长针刺住织物边，短针阻止织物边继续向下刺入。长短针向外倾可防止刺人的织物边受到纬向拉力后引起脱针。这样，织物就不能再做纬向移动。</span></p><p style="text-align: center;
