Equipment for fixing an elastic clamp band

Equipment for positioning a resilient clamping band (1) with two lugs (5) adapted for the repetitive mounting of a flexible pipe (12) on piping (13), comprising:

• a manual extraction and positioning tool with jaws,
• an automatic dispenser (2) storing plural clamping bands (1) and positioning each clamping band (1) such that the two lugs (5) of each clamping band will be accessible from an exterior of the dispenser,
• the dispenser allowing each clamping band to be gripped by the jaws (9, 52, 103) of the manual extraction and positioning tool (8, 50, 100), the tool having an approach to compress the lugs (5) of the clamping band (1) obtained by external actuating means (11) that are separately controlled,
• the tool (8, 50, 100) comprising
• means to permit the free and non-reversible approach of the jaws (9, 52, 103) toward each other when the external actuating means (11) are actuated, and
• means to release the jaws directly or progressively, at a desired time, by an external control (14, 123), wherein,
• repetitive mounting of flexible pipes (12) on piping (13) the from dispenser (2) of the clamping bands (1) by the tool (8) may be accomplished by the successive steps of:
• a) emplacing the jaws (9) of the tool on the lugs (5) of a first clamping band (1) presented by the dispenser (2),
• b) pre-locking the jaws (9) of the tool against the lugs (5) of said first clamping band (1) to bring the first clamping band into an open position thanks to the external actuating means (11),
• c) automatically holding the jaws in the pre-locking position,
• d) withdrawing from the dispenser (2) the first clamping band held open by the hand tool (8), a second clamping band (1) being automatically placed in position for a further extraction by the dispenser,
• e) positioning the open first clamping band (1) about the flexible pipe (12),
• f) releasing the locking of the jaws (9) of the tool (8), which is provided for this purpose with the external control (14) to close the clamping band (1) on the flexible pipe (12) to cause the first clamping band to lock on the piping (13), and
• g) disengaging the tool (8) for a new operation.
