Abstract
Abstract A device for applying a section of pressure sensitive tape as a cover over the surface of a test tray having a multiplicity of upwardly open wells comprises a base having a sealing zone intermediate a tray loading zone and a tray removal zone. The tray is placed on a slide guide at the loading zone and moved to the sealing zone where a rotatable resiliently surfaced feed roller presses the leading end of the tape upon and along the top surface of the tray while moving the tray through the device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
249 words
A device for applying a cover over the surface of a test tray having a multiplicity of upwardly open wells, comprising a base having a sealing zone intermediate a tray loading zone and a tray removal zone, means rotatably mounting a roll of tape in the upper part of said sealing zone, slide guide means on said loading zone leading to said sealing zone, feed means in said sealing zone for applying the leading end of said tape upon and along the top surface of said tray while moving said tray along said slide guide means to said removal zone comprising a rotatable feed roller disposed for pressing the leading end of said tape onto the top surface of said moving tray, and a tape guide pin or roller mounted on a fixed axis below said tape roll at the loading zone side of said sealing zone for tensioning the tape from said roll and directing the leading end of said tape at a predetermined angle to the underside of said feed roller while affixing the tape thereto, rotation of said roller serving to draw tape from said roll over said guide pin or roller and to slidably displace said tray through said sealing zone, and means movably mounted at said base for holding the leading end of the tape against said roller, said holding means being positioned so as to be engaged by the tray and moved to inoperative position when the tray passes through said sealing zone.
Claim 2
Independent Claim
249 words
A device for applying a cover over the surface of a test tray having a multiplicity of upwardly open wells, comprising a base having a sealing zone intermediate a tray loading zone and a tray removal zone, means rotatably mounting a roll of tape in the upper part of said sealing zone, slide guide means on said loading zone leading to said sealing zone, feed means in said sealing zone for applying the leading end of said tape upon and along the top surface of said tray while moving said tray along said slide guide means to said removal zone comprising a rotatable feed roller disposed for pressing the leading end of said tape onto the top surface of said moving tray, and a tape guide pin or roller mounted on a fixed axis below said tape roll at the loading zone side of said sealing zone for tensioning the tape from said roll and directing the leading end of said tape at a predetermined angle to the underside of said feed roller while affixing the tape thereto, rotation of said roller serving to draw tape from said roll over said guide pin or roller and to slidably displace said tray through said sealing zone, and means movably mounted at said base for holding the leading end of the tape against said roller, said holding means being positioned so as to be engaged by the tray and moved to inoperative position when the tray passes through said sealing zone.
Claim 3
Dependent Claim
15 words
The device defined in claim 1, wherein said feed roller has a deformable peripheral surface.
Claim 4
Dependent Claim
35 words
The device defined in claim 1, wherein said tape is pressure sensitive and is threaded under said roller with the non-stickly surface engaging said roller and the sticky surface facing the path of said tray.
Claim 5
Dependent Claim
23 words
The device defined in claim 1, wherein said holding means is a pivoted member spring biased to urge the tape against said roller.
Claim 6
Dependent Claim
37 words
The device defined in claim 1, wherein cutting means is mounted above said base and is operable for slitting the tape at the trailing end of the tray after the tray has passed to the removal zone.
Claim 7
Dependent Claim
48 words
The device defined in claim 1, wherein the removal zone has a platform at the same level as said slide guide means for slidably receiving said covered tray and an abutment for stopping tray movement after the top surface of the tray has been covered by said tape.
Claim 8
Dependent Claim
49 words
The device defined in claim 1, wherein a pair of arms extend upright from the base at said sealing zone and are formed with said means for rotatably mounting a supply roll of said tape, a said feed roller is rotatably mounted on said arms below said supply roll.
