Abstract
The present invention generally provides for an apparatus and method for heat shrinking an envelope of heat shrinkable sleeving material into circumferential and longitudinal conformity with a substrate product enclosed by the sleeving material. The present invention provides for a sleeve gripping/holding tool and sleeving table apparatus combination used during the heat shrinking method of the invention for enabling the tensioning and positioning of a heat shrinkable sleeve during the heat application process.
Claims60
A system for applying a heat shrink sleeve to a substrate product comprising:
- a heat source means, adjacent to the sleeve, for applying heat to the sleeve;
- a releasable gripping means, attached to the sleeve, for holding the sleeve during application of the heat source;
- and
- a variable tensioning means, attached to the gripping means, for applying a tensioning force to the sleeve along a longitudinal axis of the sleeve.
An apparatus for radially shrinking a sleeving material onto a substrate comprising:
- a heater adjacent to the material;
- a clamp releasably connected to the material;
- a tensioning device functionally connected to the clamp;
- and
- wherein the tensioning device is variably adjustable to provide a continuous tension force to the clamp.
A method of shrinking a heat shrinkable material onto a product, the method comprising the steps of:
- sizing the material;
- placing the material onto the product;
- applying heat to the material;
- applying a continuously variable tension to the material in order to provide generally uniform radial contraction and prevent axial contraction of the material.
An apparatus for applying a heat shrinkable material tube to a substrate comprising:
- a clamping means for holding the heat shrinkable material;
- a tension transmission means, attached to the clamping means, for transmitting a tension force to the clamping means;
- a tension generating means, attached to the tension transmission means and directly adjacent to the clamping means, for creating the tension force;
- a heating means, adjacent to the heat shrinkable material, for heating the heat shrinkable material.
