Abstract: A bag holder (75) is adapted to hold a flexible bag (B) in an upright and open position. The bag holder includes a wire-frame member (78) having a back portion, a top portion, a left side portion, and a right side portion, and a bag bottom support (91, 82) adapted to be mounted on the frame. The bag bottom support may be mounted on the frame in different positions so as accommodate different size bags.

Abstract: The present invention provides a portion of a die assembly (20) for use in the extrusion of foamed polystyrene. The die assembly includes a first plate (21), a second plate (22), and an insert (23). The first plate has an upstream face (24), a downstream face (25), and a first opening (26) extending between the two first plate faces. The walls (28) of this opening are divergent in a downstream direction. The second plate has an upstream face (29) arranged to abut the first plate downstream face, a downstream face (30), and a second opening (31) extending between the second plate faces and communicating with the first opening. The second opening is bounded by non-divergent walls (32). The insert has a forward marginal end portion mounted on the first plate in the first opening, and has a rearward marginal end portion arranged in the second opening.
