摘要： A device for making a molded stair tread is described. The device can have: a base; a pivoting assembly; a molding template connected to the pivoting assembly; a holding device connected to the molding template, the holding device having a clamp jaw and a pivot configured to rotate the holding device relative to the molding template; and a locking mechanism configured to hold the molding template and the holding device in an open configuration such that the holding device can accept a first part of the plastic sheet and configured to release the molding template and the holding device such that the holding device is in a securing configuration that secures, via the clamp jaw, the first part of the plastic sheet to the first side of the molding template at the first longitudinal edge of the molding template. Methods for making the stair tread are described as well as the molded stair tread.
