Abstract: In a mold comprising separable mold parts, one of the mold parts is formed with an elongated first slot opening into the mold cavity and a similarly elongated second slot in the bottom of the first slot and of narrower width than the first slot. A substantially hard non-deformable stiffening member is removably held in the second slot with a free edge projecting into the mold cavity, and a deformable profile strip of U-shaped cross-section is supported on this member with its closed maximum width portion extending across the free edge of said member within the mold cavity and with its legs received in the first slot on opposite sides of said member. When an article is then formed in the mold cavity and stripped from the mold, it withdraws both profile strip and the stiffening member from the respective slots, whereupon removal of the stiffening member from the deformable profile strip allows substantial deformability of the profile strip into the space formerly occupied by the stiffening member so that the profile strip may then be withdrawn through the narrow open side of the undercut slot formed by it in the article.
Abstract translation: 在包括可分离的模具部件的模具中，模具部件中的一个形成有在模腔中的细长的第一狭槽和在第一槽的底部中的类似的细长的第二槽，并且具有比第一槽窄的宽度。 基本上硬的不可变形的加强构件可移除地保持在第二槽中，具有突出到模腔中的自由边缘，并且U形横截面的可变形轮廓带被支撑在该构件上，其闭合的最大宽度部分延伸跨越 所述构件在模具腔内的自由边缘并且其腿部容纳在所述构件的相对侧上的第一狭槽中。 当制品在模具腔中形成并从模具中剥离时，它从相应的狭槽中取出型材条和加强件，从而从可变形的型材条移除加强件允许型材带材进入到 先前由加强构件占据的空间，使得轮廓带可以通过其在制品中形成的底切槽的窄开口侧被抽出。
