The present disclosure relates to an apparatus and method for assembling elastic laminates that can be used to make absorbent article components. Certain aspects of the present disclosure relate to anvils and spreader mechanisms adjacent the anvils. During assembly, a first substrate may be advanced in the longitudinal direction onto the rotating anvil. A spreader mechanism is used to activate an elastic material by stretching the elastic material in a transverse direction to a first elongation. The elastic material is then consolidated in the transverse direction to a second elongation, wherein the second elongation is less than the first elongation. The consolidated elastic material is then bonded between the first substrate and the second substrate on the anvil. In some configurations, the first substrate and the second substrate may be non-woven fabrics, and the elastic material may be an elastic film and/or an elastic laminate. 本公开涉及用于装配可用来制备吸收制品部件的弹性层合体的设备和方法。本公开的特定方面涉及砧和邻近砧的撒布机机构。在装配过程中，第一基底可沿纵向被推进到旋转的
