Abstract

Abstract An apparatus for processing a double face adhesive tape so as to attach at least one member thereto, comprising a roll of the double face adhesive tape having release papers attached to both faces, a drawing out means of the double face adhesive tape from said roll, a slitting means to slit at least the vicinity of one side edge of the upper release paper or the lower release paper of the double face adhesive tape parallel to said side edge, a separating means to separate the slit release paper leaving at least one side portion of the slit release paper attached, and an attaching means to attach at least one member on the exposed face of the double face adhesive tape is disclosed. The drawing out means intermittently draws out the double face adhesive tape from the roll, and a punching means to punch the double face adhesive tape to form hole(s) is further incorporated. Also provided are a cutting means to cut the remaining release paper and the double face adhesive tape to a size smaller than the attached face of said member and a detaching means to detach the member and the cut release paper and the cut double face adhesive tape from the double face adhesive tape.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 151 words
In an apparatus for processing a double face adhesive tape whereby at least one face of a member is attached thereto, comprising a roll of the double face adhesive tape having release papers attached to both faces, a drawing out means of the double face adhesive tape from said roll, a separating means to separate the release paper from one of said faces of said tape, an attaching means to attach at least one member on the exposed adhesive face of the double face adhesive tape where the release paper has been removed, the improvement which comprises incorporating a cutting means to cut the remaining release paper and the double face adhesive tape in a size being smaller than the attached face of said member and a detaching means to detach the member and the cut release paper and the cut double face adhesive tape from the double face adhesive tape.
Claim 2
Dependent Claim 151 words
In an apparatus for processing a double face adhesive tape whereby at least one face of a member is attached thereto, comprising a roll of the double face adhesive tape having release papers attached to both faces, a drawing out means of the double face adhesive tape from said roll, a separating means to separate the release paper from one of said faces of said tape, an attaching means to attach at least one member on the exposed adhesive face of the double face adhesive tape where the release paper has been removed, the improvement which comprises incorporating a cutting means to cut the remaining release paper and the double face adhesive tape in a size being smaller than the attached face of said member and a detaching means to detach the member and the cut release paper and the cut double face adhesive tape from the double face adhesive tape.
Claim 3
Dependent Claim 57 words
The apparatus of claim 1 wherein said member is the lower frame of an ionic activity-measuring device, and which further comprises a separating means to separate the remaining release paper and an attaching means to attach a second frame on the exposed adhesive face of the double face adhesive tape where the release paper has been removed.
Claim 4
Dependent Claim 62 words
The apparatus of claim 1 wherein said member is an upper frame of an ionic activity-measuring device, and which further comprises a separating means to separate the remaining release paper and an attaching means to attach a lower frame of an ionic activity-measuring device on the exposed adhesive face of the double face adhesive tape where the release paper has been removed.
Claim 5
Dependent Claim 67 words
The apparatus of claim 1 which further comprises a slitting means to slit at least the vicinity of one side edge of the release paper from one face of the double face adhesive tape parallel to said side edge, and said separating means is to separate the slit release paper leaving at least one of the side portion of the slit release paper attached to the tape.
Claim 6
Dependent Claim 21 words
The apparatus of claim 4 wherein said member is liquid-distributing member(s) and a frame to receive themof an ionic activity-measuring device.
Claim 7
Dependent Claim 20 words
The apparatus of claim 4 wherein said member is a frame to receive liquid-distributing member(s) of an ionic activity-measuring device.
