Sealing appliance
View Patent ↗An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.
1. A process for sealing and allowing separation of a sealing device on a hollow hose, comprising:
placing a hollow hose of elastic material, having a sealing device applied to the hose, between two jaws of a hand-held appliance, the two jaws capable of being moved relative to each other, at least one of the jaws supporting at least one bar projecting toward the opposite jaw, and at least one of the jaws supporting a cutting indication projection different from said bar and which projects toward the other jaw;
causing relative movement of the jaws toward each other to make an indentation with said bar, along a straight line transverse to the sealing device, in the sealing device and the hollow hose to reinforce the sealing thereof, fixing the sealing device on the hose, and forming a cutting indication in the sealing device with said cutting indication projection to allow cutting of the hose, wherein said indentation and said cutting indication are formed without longitudinal relative movement between the appliance and said hollow hose and said sealing device.
2. The process of claim 1 , further comprising making at least two substantially transverse indentations in the sealing device and hose with at least two bars extending along a straight line and disposed on the jaws wherein said at least two bars have projecting ends which are arranged substantially in parallel at a distance from each other and extend substantially transversely to the longitudinal direction of the sealing device.
3. The process of claim 2 , further comprising making a substantially transverse cutting indication in the sealing device and the hose with the cutting indication projection, wherein the cutting indication projection extends substantially transversely to the longitudinal direction of the sealing device.
4. The process of claim 1 , further comprising positioning the sealing device and the hose between the jaws with a fixture, the fixture being disposed on at least one of the jaws.
5. The process of claim 1 , wherein the at least one bar and the cutting indication projection are situated on said one jaw, and the fixture is situated on the other jaw.
6. The process of claim 1 , wherein the cutting indication projection co-operates with an opposite recess in the jaw opposite the cutting indication projection.
7. The process of claim 1 , wherein the cutting indication projection is disposed between two bars.
8. The process of claim 1 , wherein the cutting indication projection is disposed on the same jaw as the at least one-bar.
9. The process of claim 1 , wherein the cutting indication projection projects past a projecting end of at least one bar when the cutting indication projection is fully engaged with the sealing device to make a cutting indication.
10. The process of claim 1 , further comprising making a complete cut in said hollow tube and said sealing device.
11. The process of claim 1 , wherein said bar is rigidly coupled to said jaw.
12. The process of claim 1 , wherein said sealing device comprises metal.
13. The process of claim 1 , wherein only one jaw moves.
14. The process of claim 1 , wherein relative movement of the jaws toward each other is caused manually.
