The present paper reviews the results from the study of spigots, i.e. cuticular spinning structures obtained by the scanning of 52 genera belonging to 28 families of araneomorph spiders. The finding of eight morphologically different forms of these structures being attached to ducts of the pyriform type of silk glands is of fundamental importance for the final conclusions. The comparative observations enable me to create a hypothesis dealing with the existence of several evolutionary lines of spiders, each of which is represented with their own form of spigots. Nevertheless the character of these spigots undoubtedly reflects phylogenetic relationships between the spider taxa. The detection of a special mechanoreceptive field on top of the anterolateral spinnerets increases the knowledge of the functional morphology of the spider's spinning apparatus.
本文回顾了对纺管的研究结果，纺管即通过扫描28个科的52个漏斗蛛属物种所获得的表皮纺丝结构。发现这些结构有八种形态不同的形式附着于梨形丝腺的导管上，这对于得出最终结论至关重要。比较观察使我能够提出一个假说，即蜘蛛存在多条进化路线，每条路线都有其独特的纺管形式。然而，这些纺管的特征无疑反映了蜘蛛类群之间的系统发育关系。在前侧纺器顶部检测到一个特殊的机械感受区域，增加了我们对蜘蛛纺丝器功能形态的了解。
