Classes 120(3) and 142(2) Apparatus for transporting wound bobbins from a winding machine to a loom having automatic bobbin-changing apparatus by means of bobbin containers which can be positioned directly thereon, comprises at least one carrying frame having compartments for the releasable insertion of a container in each thereof and guides on the winding machine and loom for. mounting the frame. As shown, a carrying frame 10 accommodates bobbin containers 30 each irreversibly located between a wall, as at 15a, and a guide element, as at 16a, at each end. Bobbins 31 are retained in each container by a spring-loaded locking flap 32 and each container is retained in the frame by engagement of a nose 22, of a leaf-spring finger 21 on a spring plate 20, with a notch 38. At the loom, Figs. 4 and 5, the frame is suspended by rims 13 on rails 40 or roller conveyers (not shown) and moves by gravity to a stop position whereat a lever 45 may be manually rocked to rotate a shaft 42 thereby causing a cam 46, or a series of cams (not shown) to engage projections 23 on fingers 21 and release noses 22 from engagement with notches 38. Filled containers 30 may then be removed from the frame and mounted on the bobbin-changing apparatus a projecting blade of which automatically forces flaps 32 into recesses 37 to release bobbins 31. The empty frame 10 is released from cam 46 and removed, to be succeeded by another loaded frame which may have already been positioned on rails 40. At the winding machine, Fig. 6, the frame 10 loaded with empty containers is mounted with rims 13 on and between rails 52 or roller conveyers (not shown) and is conveyed by gravity under the automatic step-by-step control of an electromagnetically operated, adjustably pivoted latch 54 which sequentially engages fingers 21 as corresponding containers 30 are successively filled with wound bobbins from a duct 51: the operation may continue uninterruptedly for successive frames 10. On the loom and the winding machine, studs or like projections may co-operate with differently formed longitudinal sides of each frame to ensure correct positioning thereof on rails 42 and 52.
