  • Patent number: 4644677
    Abstract: The present invention is a baiting machine using entire fishes. The machine combines a guide known for the guiding of the point of the fish hooks, a corridor for the introduction of the baiting fish which is perpendicular to the trajectory of the fish hook point, a retractable wall prolongating the wall of the corridor on the downstream side of the trajectory of the fish hook and a second wall perpendicular to the first, said second wall being prolongated by an arm which can be caught by the fish hook in order to pivot the retractable wall about a pivoting axis situated toward the corridor and downstream with respect to the trajectory of the fish hook and an oblique ramp pushing back the head of the bait introduced along the longitudinal direction of the corridor toward the second wall of the retractable wall. The machine is usable for trawl line fishing.

  • Patent number: 4631850
    Abstract: The invention relates to an automatic apparatus for sorting out the deformed fish hooks or those having a broken point on the so-called trawl line. The apparatus comprises a fish hook positioning device bringing the fish hook (3) to circulate by being pulled by a leader (2) and guided by the shank (4) in a slide (15), where the transverse section corresponds. The slide is of a transverse section corresponding to the normal curvature (5) of the fish hook when the shank (4) is disposed in the axial direction of the channel of slide (15); the point and barb (6) circulating inside the slide and at least a first detector (40) of any type detects, in the case of a non broken fish hook, the presence of the point and the barb (6), other detectors being adapted for detecting the deformation of the shank and a selecting device (16) controlled by said detectors discriminates the non usable fish hook. The invention allows the automatic checking of the state of trawl lines.
