Cylinder cleaning device and cylinder cleaning fabric used therefor

A cylinder cleaning device for cleaning a circumferential surface of a cylinder by pressing a cleaning fabric passed between cleaning fabric supplying element for said cleaning fabric and cleaning fabric take-up shaft assembly for taking up said cleaning fabric against said circumferential surface of said cylinder, comprising:

• a frame;
• and
• said cleaning fabric take-up shaft assembly, supported by said frame, that includes separated shaft members and shaft member fixing means for fixing said shaft members in a condition where a diameter is increased;
• and
• a wedge member inserted between said separated shaft members to increase said diameter.

A cylinder cleaning device for cleaning a circumferential surface of a cylinder by pressing a cleaning fabric passed between cleaning fabric supplying element for said cleaning fabric and cleaning fabric take-up shaft assembly for taking up said cleaning fabric against said circumferential surface of said cylinder, comprising:

• a frame;
• and
• said cleaning fabric take-up shaft assembly, supported by said frame, that includes a mechanical structure for changing a configuration thereof to mechanically change a condition in contact with said cleaning fabric, which is wound up around said cleaning fabric take-up shaft assembly, said mechanical structure consisting of shaft members, a projection engagement member provided to be retractable relative to said outer surface of said shaft member, and an inflation member for permitting said projection engagement member to be reciprocally projected from, and retracted into, said outer surface of said shaft member,
• wherein said cleaning fabric is wound around said projection engagement member that is projected from said shaft members while said inflation member is expanded, and wherein, after winging of said cleaning fabric is completed, said inflation member is shrunk and said projection engagement member is retracted from said outer surface of said shaft member to disengage said projection engagement member from said cleaning fabric.

A cylinder cleaning device for cleaning a circumferential surface of a cylinder by pressing a cleaning fabric passed between cleaning fabric supplying element for said cleaning fabric and cleaning fabric take-up shaft assembly for taking up said cleaning fabric against said circumfertial surface of said cylinder, comprising:

• a frame;
• and
• said cleaning fabric take-up shaft assembly, supported by said frame, that includes a mechanical structure for changing a configuration thereof to mechanically change a condition in contact with said cleaning fabric, which is wound up around said cleaning fabric take-up shaft assembly, with said mechanical structure including shaft members, a moving member formed to be retractable relative to said outer surface of said shaft member, an engagement member provided on said outer surface of said shaft member and coupled with said moving member, and an inflation member for permitting said moving member to be projected from, and retracted into, said outer surface of said shaft member,
• wherein said cleaning fabric is wound around said projection engagement member that is separated from said shaft members while said inflation member is expanded, and wherein, after winging of said cleaning fabric is completed, said inflation member is shrunk and said moving member is retracted from said outer surface of said shaft member to disengage said engagement member from said cleaning fabric.

• a frame;
• and
• said cleaning fabric take-up shaft assembly, supported by said frame, that includes a mechanical structure for changing a circumference of said cleaning fabric take-up shaft assembly thereof to mechanically change a condition in contact with said cleaning fabric, which is wound up around said cleaning fabric take-up shaft assembly, with said mechanical structure consisting of a shaft member, for which a groove of a predetermined width is formed in an outer surface or said shaft in the axial direction thereof, and a bar member, which is inserted into said groove of said shaft member so that said cleaning fabric contacts one part of an outer surface during the winding of said cleaning fabric, and which has at least one end detachably attached to an end of said shaft member,
• wherein said bar member is taken out from said shaft member and said shaft member is removed from said wound cleaning fabric.
