Abstract
Abstract An apparatus for splicing together two large sheets of material, e.g., seismic sections, where one operator can carry out the splicing operation. The apparatus is comprised of a work surface onto which the material is positioned and held in place by vacuum and mechanical means. A carriage, mounted on guide means which extend across the work surface, has a knife which cuts the material along a desired line as the carriage moves in a first direction and adhesive dispensing means to apply tape to the material along said desired line as the carriage moves in the opposite direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
An apparatus for splicing two sheets of material together in a desired relationship, said apparatus comprising: a work surface on which said sheets can be positioned in said desired relationship; a splicing assembly extending across said work surface, said assembly comprising: a track extending across said work surface, said track having a cutting groove therein; guide means extending across said work surface above said track; means for securing said sheets on said work surface so that the common line of those portions of said sheets to be spliced overlies said cutting groove; and a carriage movably mounted on said guide means, said carriage comprising: means for cutting said sheets along said common line when said carriage is moved in a first direction along said guide means; and means for applying adhesive tape material to said sheets along said common line to secure said sheets together in said desired relationship when said carriage is moved in a second opposite direction along said guide means; means for moving said carriage along said guide means in said first and said seind directions.
Claim 2
Independent Claim
179 words
An apparatus for splicing two sheets of material together in a desired relationship, said apparatus comprising: a work surface on which said sheets can be positioned in said desired relationship; a splicing assembly extending across said work surface, said assembly comprising: a track extending across said work surface, said track having a cutting groove therein; guide means extending across said work surface above said track; means for securing said sheets on said work surface so that the common line of those portions of said sheets to be spliced overlies said cutting groove; and a carriage movably mounted on said guide means, said carriage comprising: means for cutting said sheets along said common line when said carriage is moved in a first direction along said guide means; and means for applying adhesive tape material to said sheets along said common line to secure said sheets together in said desired relationship when said carriage is moved in a second opposite direction along said guide means; means for moving said carriage along said guide means in said first and said seind directions.
Claim 3
Dependent Claim
58 words
The apparatus of claim 1 wherein said means for securing said sheets on said work surface includes: slots in said work surface extending parallel to said track, said slots adapted to be fluidly connected to a vacuum source; and holddown means positioned parallel to said track and being movable into and out of contact with said work surface.
Claim 4
Dependent Claim
61 words
The apparatus of claim 2 wherein said means for cutting said sheets includes: knife means pivotally mounted on said carriage; knife actuating means to move said knife means into said cutting groove on said track when said knife actuating means is actuated; and means to move said knife means out of said cutting groove when said knife activating means is deactuated.
Claim 5
Dependent Claim
12 words
The apparatus of claim 3 wherein said actuating means comprises: a solenoid.
Claim 6
Dependent Claim
91 words
The apparatus of claim 4 wherein said means for applying adhesive tape material includes: a tape reel rotatably mounted on said carriage; a tape arm pivotally mounted on said carriage, said tape arm adapted to receive tape from said tape reel; tape actuating means for moving said tape arm into contact with said track means so that tape can be dispensed along said cutting groove when tape actuating means is actuated; and means for moving said tape arm out of contact with said track when said tape actuating means is deactuated.
Claim 7
Dependent Claim
13 words
The apparatus of claim 5 wherein said tape actuating means comprises: a solenoid.
Claim 8
Dependent Claim
47 words
The apparatus of claim 6 including: tape cutting means mounted on said carriage comprising: tape knife movably mounted on said carriage, said knife being positioned so that when actuated said knife will cut the tape dispensed from said tape reel; and means to actuate said tape knife.
Claim 9
Dependent Claim
38 words
The apparatus of claim 7 including: switch means at either end of said track to stop movement of said carriage in either said first or second direction when said carriage has completed desired travel in said respective direction.
Claim 10
Dependent Claim
57 words
The apparatus of claim 8 including: notches in said track means at a point where said carriage completes movement in said first direction, said notches adapted to temporarily engage the loose end of tape from said tape reel to reverse the sides of the tape in contact with said track when carriage moves in said second direction.
Claim 11
Dependent Claim
35 words
The apparatus of claim 9 wherein at least a portion of said work surface is comprised of translucent material, and lighting means under said work surface for illuminating said translucent portion of said work surface.
