Abstract

A manually-operable crimping tool for lockingly securing a seal member upon overlapped end portions of plastic strapping is provided with particular structure such that the resulting crimped seal member and overlapped end portions of the plastic strapping have an undulated configuration whereby the overlapped end portions of the plastic strapping cannot readily become loosened or disengaged with respect to each other under the influence of axially applied tensile forces. The present invention is also directed toward the particularly structured or configured seal member as well as toward the resulting sealed joint formed or defined between the seal member and the overlapped end portions of the plastic strapping.

Dependent claims

A manually-operable tool for applying a seal member to overlapped end portions of plastic strapping material, comprising:

a pair of handles pivotally connected together about an axis defining an axial direction so as to be movable between relatively opened and relatively closed positions;
an anvil having a predetermined axial extent and a transverse extent;
a pair of jaws pivotally mounted upon opposite transverse end portions of said anvil between relatively opened and relatively closed positions and operatively connected to said pair of handles such that when said pair of handles are moved to their relatively opened positions, said pair of jaws are correspondingly moved to their relatively opened positions, and when said pair of handles are moved to their relatively closed positions, said pair of jaws are correspondingly moved to their relatively closed positions;
and
undulating structure formed upon each one of said anvil and said pair of jaws so as to extend in said axial direction and for cooperating together so as to form an undulated crimped joint upon overlapped end portions of plastic strapping when a seal member and overlapped end portions of plastic strapping are disposed between said anvil and said pair of jaws, and when said pair of jaws are moved to their relatively closed positions.

A manually-operable tool for applying a seal member to overlapped end portions of elongated material, comprising:

a pair of handles pivotally connected together about an axis defining an axial direction so as to be movable between relatively opened and relatively closed positions;
an anvil having a predetermined axial extent and a transverse extent;
a pair of jaws pivotally mounted upon opposite transverse end portions of said anvil between relatively opened and relatively closed positions and operatively connected to said pair of handles such that when said pair of handles are moved to their relatively opened positions, said pair of jaws are correspondingly moved to their relatively opened positions, and when said pair of handles are moved to their relatively closed positions, said pair of jaws are correspondingly moved to their relatively closed positions;
and
undulating structure formed upon each one of said anvil and said pair of jaws so as to extend in said axial direction and for cooperating together so as to form an undulated crimped joint upon overlapped end portions of elongated material when a seal member and overlapped end portions of the elongated material are disposed between said anvil and said pair of jaws, and when said pair of jaws are moved to their relatively closed positions.
