METHOD AND DEVICE FOR ERECTING A PACKAGING SLEEVE

摘要

An erecting device (4) for erecting a packaging sleeve (3) comprising a magazine (20) for holding a plurality of the sleeves in a collapsed state (6) in a stack. A dispensing outlet (22) from the magazine (20) accommodates the sleeves (6) sequentially from the magazine (20). A transfer mechanism (35) withdraws the sleeves (6) sequentially from the magazine (20) into a former (25) within which the sleeves (6) are erected. Restraining lips (23) located on opposite sides of the dispensing outlet (22) support the collapsed sleeves (6) in the magazine (20) and urge the side edges (17) of each collapsed sleeve (6) towards each other as it is being withdrawn through the dispensing outlet (22) for urging leaves (14 and 15) of the collapsed sleeve (6) apart for facilitating erection of the sleeve (3) in the former (25).
