Abstract
The device is a tool for placing a split sheath around elongated items such as bundles of electronic cables. It comprises a guide bush which makes possible the opening of the sheath, a duct for the cables to be sheathed, lateral grooves for guiding the open sheath and is characterized by the presence of a lateral opening which allows the introduction or extraction of cables possibly already fixed at their two extremities during the use of the tool, as well as by the angle which there is between this opening and the duct for the cables in a manner to keep them in position in the tool be their own rigidity. The tool may have a handle for manipulation and for setting the tool in relative motion along the cables to be sheathed. The invention is also directed at the method for using the tool.
Claims12
Device for insertion of elongated items into a tubular sheath having a longitudinally extending self-closing slit having edges, wherein insertion is accomplished by movement of the device longitudinally with respect to the slit, the device comprising:
- an elongated head, having a longitudinal axis and top, bottom and sides, and including a guide portion disposed on said axis, said head being extendible through said longitudinal slit into said sheath to open said sheath by separating the edges of the slit and to guide said edges upon movement along the slit;
- a feed duct for receiving elongated items, said feed duct extending through the head to said guide portion and having an axis located at a first angle obliquely disposed in relation to the longitudinal axis of the head, and a lateral passage, having a lateral opening to one of said sides of the device, said lateral passage intersecting the feed duct and communicating therewith for introduction into and extraction of elongated items out of said feed duct and being inclined with respect to the longitudinal axis of the head at a second angle different from the first angle.
A method for insertion of elongated items into a tubular sheath having a longitudinally extending self-closing slit having side edges, wherein insertion is accomplished by movement of an insertion device longitudinally with respect to the slit, wherein the device comprises an elongated head, having a longitudinal axis and a top, bottom and sides, and including a guide portion disposed on said longitudinal axis, the device further comprising a feed duct for said elongated items extending through the head to said guide portion and having an axis located at a first angle obliquely disposed in relation to the longitudinal axis of the head, and a lateral passage, a lateral opening to said lateral passage through one of said sides of the head of said device, said lateral passage intersecting the feed duct and being inclined with respect to the longitudinal axis of the head at a second angle different from the first angle, wherein the method comprises the steps of:
- (a) extending the head through said longitudinal slit into said sheath to open said sheath by separating the edges of the slit and to guide said edges upon movement along the slit;
- (b) introducing elongated items into a lateral passage of the device and subsequently feeding said items into a feed duct extending through said device head, opening of the sheath by the guide portion and guiding of the sheath along the head of the device by effecting relative movement between the sheath and the device;
- and
- c) feeding the sheath relative to the device until the items are covered by virtue of relative movement of the sheath, or of the assembly of the sheath and items to be sheathed, with regard to the device.
