Abstract

Abstract There is disclosed herein an apparatus for use in thermally binding documents. The apparatus includes a housing which defines a document receiving aperture. Biased supports are associated with the housing and in alignment with the aperture for compressing documents along an edge to be bound and for defining a predetermined binding position. A heater is associated with the housing and is positioned adjacent the predetermined position and support for heating the edge of the documents to be bound.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 198 words
An apparatus for use in thermally binding documents, said apparatus including: means defining a housing; means associated with the housing which define a receiving aperture for receiving documents to be bound; support means associated with said housing and aligned with the receiving aperture means for compressing documents together along the edge to be bound and for supporting documents in a predetermined position; heating means associated with said housing and adjacent said predetermined positioning and support means for heating the edge of said documents to be bound; said support means including a pair of spaced, downwardly extending support plate-like means which are biased toward each other for grasping documents therebetween; said plate-like means including a pair of flexible plate members, each secured at one end to said housing adjacent said document receiving aperture and spaced from each other and each of the other ends being free and resiliently biased toward each other to cooperate in defining said predetermined position; said plate-like means being constructed to converge from said document receiving end toward said binding end and form a V-like shape; and said housing means, said receiving aperture defining means and support means being unitary and formed of a plastic.
Claim 2
Independent Claim 198 words
An apparatus for use in thermally binding documents, said apparatus including: means defining a housing; means associated with the housing which define a receiving aperture for receiving documents to be bound; support means associated with said housing and aligned with the receiving aperture means for compressing documents together along the edge to be bound and for supporting documents in a predetermined position; heating means associated with said housing and adjacent said predetermined positioning and support means for heating the edge of said documents to be bound; said support means including a pair of spaced, downwardly extending support plate-like means which are biased toward each other for grasping documents therebetween; said plate-like means including a pair of flexible plate members, each secured at one end to said housing adjacent said document receiving aperture and spaced from each other and each of the other ends being free and resiliently biased toward each other to cooperate in defining said predetermined position; said plate-like means being constructed to converge from said document receiving end toward said binding end and form a V-like shape; and said housing means, said receiving aperture defining means and support means being unitary and formed of a plastic.
Claim 3
Dependent Claim 23 words
An apparatus as in claim 1, wherein each of said plate members is secured to said housing adjacent said receiving aperture defining means.
Claim 4
Dependent Claim 30 words
An apparatus as in claim 2, wherein said free ends of said plate means are separable so as to receive documents of various thicknesses therebetween and urge said documents together.
Claim 5
Dependent Claim 24 words
An apparatus as in claim 1, wherein said document receiving means define an elongated slot which extends substantially across the width of the housing.
Claim 6
Dependent Claim 34 words
An apparatus as in claim 3, wherein said biased free ends are constructed to engage said documents, urge said documents together and apply a compressive force on said documents at said predetermined binding position.
Claim 7
Independent Claim 200 words
An apparatus for use in a thermal binding machine for binding documents along an edge comprising: a unitary housing which includes: a base; a front face; a back edge which is higher from the base than a front edge and which is elongated in the transverse direction; a sloped face interconnecting the front face and back edge; means defining an elongated transversely extending document receiving slot positioned in the front face closer to the back edge than the front edge; a pivotal plate-like support means associated with said slot means and extending from said slot means toward said base, said plate-like support means each having a secured end adjacent said slot and a free end, each of said free ends biased toward each other so as to cooperate in defining a binding position, said plate-like support means defining a converging V-like shape, said free ends being separable so as to accommodate various quantities of documents therebetween and exert a compressive force thereon at said binding position; and heating means adjacent the free ends of said plate-like support means and positioned between said free ends and said base for cooperating in thermally binding said documents and in defining said binding position.
Claim 8
Independent Claim 200 words
An apparatus for use in a thermal binding machine for binding documents along an edge comprising: a unitary housing which includes: a base; a front face; a back edge which is higher from the base than a front edge and which is elongated in the transverse direction; a sloped face interconnecting the front face and back edge; means defining an elongated transversely extending document receiving slot positioned in the front face closer to the back edge than the front edge; a pivotal plate-like support means associated with said slot means and extending from said slot means toward said base, said plate-like support means each having a secured end adjacent said slot and a free end, each of said free ends biased toward each other so as to cooperate in defining a binding position, said plate-like support means defining a converging V-like shape, said free ends being separable so as to accommodate various quantities of documents therebetween and exert a compressive force thereon at said binding position; and heating means adjacent the free ends of said plate-like support means and positioned between said free ends and said base for cooperating in thermally binding said documents and in defining said binding position.
Claim 9
Dependent Claim 47 words
An apparatus as in claim 6, wherein there is further provided document guide means which comprise an upstanding guide element extending upwardly from said front face transversely thereof adjacent said slot and along the edge of said slot adjacent the front side edge of said slot means.
