Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
197 words
A device for taping a cover onto a drum comprising a base plate and means mounting the base plate on the cover for rotational movement on an axis corresponding to the axis of the cover, an arm pivotally mounted on the base plate for rocking movement relative to the base plate, a pressure roller mounted on the arm for free rotational movement, a tape supply roll support mounted on the arm for free rotational movement of a supply roll, a guide post fixed to the arm intermediate the support and the pressure roller and offset inwardly towards the periphery of the cover from a line between the axes of said support and pressure roller so that the tape comes into engagement with the guide post during passage from the supply roll to the pressure roller, and means constantly urging the arm for rocking movement about its pivot in a direction to displace the pressure roller inwardly towards the periphery of the cover, in which the guide post depends from the arms and in which the lower end portion of the guide post is formed with an outward flare to preform the tape as it is drawn thereover.
Claim 2
Independent Claim
197 words
A device for taping a cover onto a drum comprising a base plate and means mounting the base plate on the cover for rotational movement on an axis corresponding to the axis of the cover, an arm pivotally mounted on the base plate for rocking movement relative to the base plate, a pressure roller mounted on the arm for free rotational movement, a tape supply roll support mounted on the arm for free rotational movement of a supply roll, a guide post fixed to the arm intermediate the support and the pressure roller and offset inwardly towards the periphery of the cover from a line between the axes of said support and pressure roller so that the tape comes into engagement with the guide post during passage from the supply roll to the pressure roller, and means constantly urging the arm for rocking movement about its pivot in a direction to displace the pressure roller inwardly towards the periphery of the cover, in which the guide post depends from the arms and in which the lower end portion of the guide post is formed with an outward flare to preform the tape as it is drawn thereover.
Claim 3
Independent Claim
282 words
A device for taping a cover onto a drum comprising a base plate and means mounting the base plate on the cover for rotational movement on an axis corresponding to the axis of the cover, an arm pivotally mounted on the base plate for rocking movement relative to the base plate, a pressure roller mounted on the arm for free rotational movement, a tape supply roll support mounted on the arm for free rotational movement of a supply roll, a guide post fixed to the arm intermediate the support and the pressure roller and offset inwardly towards the periphery of the cover from a line between the axes of said suppport and pressure roller so that the tape comes into engagement with the guide post during passage from the supply roll to the pressure roller, means constantly urging the arm for rocking movement about its pivot in a direction to displace the pressure roller inwardly towards the periphery of the cover and means for cutting the tape, in which the cutting means is incorporated in the guide post and comprises a guide post in the form of a hollow sleeve section, a rod mounted for axial movement in the sleeve section between raised and lowered positions of adjustment with a portion of the rod extending above the sleeve section, a knife extending outwardly from the rod through an elongate slot in the sleeve section, means constantly urging the rod towards raised position whereby the knife is out of alignment with the portion of the rod engaged by the tape, and means for actuating the rod from raised to lowered position to sever the portion of the tape in engagement with the post.
Claim 4
Independent Claim

A device for taping a cover onto a drum comprising a base plate and means mounting the base plate on the cover for rotational movement on an axis corresponding to the axis of the cover, an arm pivotally mounted on the base plate for rocking movement relative to the base plate, a pressure roller mounted on the arm for free rotational movement, a tape supply roll support mounted on the arm for free rotational movement of a supply roll, a guide post fixed to the arm intermediate the support and the pressure roller and offset inwardly towards the periphery of the cover from a line between the axes of said suppport and pressure roller so that the tape comes into engagement with the guide post during passage from the supply roll to the pressure roller, means constantly urging the arm for rocking movement about its pivot in a direction to displace the pressure roller inwardly towards the periphery of the cover and means for cutting the tape, in which the cutting means is incorporated in the guide post and comprises a guide post in the form of a hollow sleeve section, a rod mounted for axial movement in the sleeve section between raised and lowered positions of adjustment with a portion of the rod extending above the sleeve section, a knife extending outwardly from the rod through an elongate slot in the sleeve section, means constantly urging the rod towards raised position whereby the knife is out of alignment with the portion of the rod engaged by the tape, and means for actuating the rod from raised to lowered position to sever the portion of the tape in engagement with the post.
Claim 5
Dependent Claim
32 words
A device as claimed in claim 2, in which the means constantly urging the rod towards raised position comprises spring means interposed between the projecting portion of the rod and the sleeve.
