Device for winding a flexible tube

Abstract

The invention relates to a device for winding a flexible tube comprising two blades LAM that are coupled in rotation about a pivoting axis PIVO appearing at the left-hand end of these blades. The device is defined such that: a blade LAM has, on its left-hand edge, a first notch En 1 which is open at the top and which is formed by a first arc of a circle Ac 1 whose origin is a connection point P2 located on the right-hand edge of this notch and on the longitudinal axis AXL of this device, the blade LAM has, on its right-hand edge, a second notch En 2 which is open at the top and which is formed by a second arc of a circle Ac 2 whose origin is a connection point P 4 located on the right-hand edge of this notch and on the longitudinal axis AXL of this device, and a diameter of these arcs of circles Ac 1, Ac 2 is supported by the longitudinal axis AXL. Moreover, one of these arcs of a circle (Ac 2 ) has an angle at the centre equal to the sum of 180° and an additional angle (K) greater than 0°.

         7 . A device for winding a flexible tube comprising two blades (LAM,  31 ,  32 ) that are coupled in rotation about a pivoting axis (PIVO) appearing at the left-hand end of said blades so that:
 one of said blades (LAM) has on its left-hand edge a first upwardly open notch (En 1 ) that is formed by a first arc of circle (Ac 1 ) whose origin is a connection point (P 2 ) located on the right-hand edge of this notch and on the longitudinal axis (AXL) of this device,   said blade (LAM) has on its right-hand edge a second upwardly open notch (En 2 ) that is formed by a second arc of circle (Ac 2 ) whose origin is a connection point (P 4 ) located on the right-hand edge of this notch and on the longitudinal axis (AXL) of this device, and   a diameter of said arcs of circle (Ac 1 , Ac 2 ) is supported by the longitudinal axis (AXL),   wherein one of said arcs of circle (Ac 2 ) has an angle at the centre that is equal to the sum of 180° and an additional angle (K) greater than 0°.   
     
     
         8 . The device according to  claim 7 , wherein said additional angle (K) is equal to 45°. 
     
     
         9 . The device according to  claim 7 , wherein said arcs of circle (Ac 1 , Ac 2 ) have identical diameters. 
     
     
         10 . The device according to  claim 7 , characterized in that a spacer is arranged on said pivoting axis (PIVO) between the two blades ( 31 ,  32 ). 
     
     
         11 . The device according to  claim 7 , wherein holder means ( 35 ) are provided that are fastened to said pivoting axis (PIVO). 
     
     
         12 . The device according to  claim 7 , wherein an abutment ( 33 ) is provided on said blade (LAM,  31 ), which abutment is perpendicular to this blade.
