Apparatus and method are provided for setting up a basket-type carrier from a collapsed state. The carrier includes pair of foldable end panels connected to opposite ends of a slotted base panel, side panels foldably connected to opposite sides of base panel, and pair of foldably connected panel sections forming a handle. Each end panel has foldably connected upper and lower sections initially in face-to-face relation. Each upper section has side segments foldably connected to ends of the panel sections. A U-shaped insert piece is assembled with the carrier and has upstanding legs extending through the slotted base panel and retaining the handle panel sections in face-to-face relation. The panel sections of the collapsed carrier are in coplanar relation and when the collapsed carrier is at a first station, external force is applied to the panel sections causing same to fold relative to one another into upright face-to-face relation. As the panel sections move to face-to-face relation, the upper and lower sections of each end panel partially unfold. The carrier is moved to a second station wherein the upper and lower sections of each end panel assume an upright coplanar relation. The carrier is moved to a third section wherein adhesive is applied to areas of the side panels. The carrier is moved to a fourth station during which the side panels are folded to upright positions and secured to the end panels. The insert piece is assembled on the carrier slotted base panel at a fifth station.

An air filter assembly is provided which comprises a compressible air pervious multi-sided filter panel and a frame therefor, the latter being adjustable from a collapsed first mode to an operative second mode. The frame of foldable sheet material includes a foraminous center section in supporting engagement with the filter panel; a marginal section delimiting the center section; and a plurality of elongated peripheral sections arranged in alternate pairs and foldably connected to an coacting with the marginal section and with each other to form a hollow verge encompassing the filter panel periphery when the frame is in the second mode. The peripheral sections form a substantially flat multiply flange overlapping and compressing the filter panel periphery when the frame is in the first mode. A first pair of alternate peripheral sections have the opposite end portions thereof overlying corresponding end portions of a second pair of alternate peripheral sections when the frame is in the first mode. When the frame is adjusted from the first mode to the second mode, the overlapped end portions of the second pair of alternate peripheral sections will abuttingly engage at an angle the corresponding end portions of the first pair of alternate peripheral sections and restrain movement of the frame from the second mode to the first mode.
