PCT No. PCT/SE95/01055 Sec. 371 Date Sep. 18, 1997 Sec. 102(e) Date Sep. 18, 1997 PCT Filed Sep. 19, 1995 PCT Pub. No. WO96/29274 PCT Pub. Date Sep. 26, 1996A strap tensioning device comprises a frame (1) with a rotatable reel (3) and a turnable command member (2). A ratchet wheel (43) is co-rotatively connected with the reel, the wheel cooperating with two spring-loaded latch elements (14, 29). When the command member (2) is turned out from the frame (1), the reel (3) is carried with it. At an opposed return movement, the reel (3) is blocked. A rotatable support roller (4) is arranged between the two side pieces (5, 5') of the frame (1). The reel (3) comprises a shaft (16) whose opposed ends are arranged in elongated holes (9). In this way, the reel (3) may be distanced from the support roller (4), whereby the device may be used for both strap tensioning and strap feeding. |
