Abstract
A support beam supports a box type beam on which there is located, essentially tangentially to the shell surface of a guide roll coordinated with it, a contact surface for the adhesive tape. Perpendicular to the contact surface, a holding slot for the adhesive tape is provided on the box-shaped beam. The adhesive tape protrudes out of this holding slot with a considerable part, of which the cover foil is removed. A blowing device or blowing channels with blowing orifices bend the part of the adhesive tape protruding out of the slot upward so that, with the support beam approaching the guide roll, this part of the adhesive tape practically is in contact with the contact surface. In this way, adhesive tape can be fastened on the web end wrapping around the guide roll.
Claims16
A device for the application of an adhesive strip on an end of a web wound on a paper roll, said adhesive strip having an adhesive surface wherein at least a portion of said adhesive surface is covered by a protective foil, said device comprising:
- a guide roll spaced from said paper roll;
- a support beam situated in closely spaced arrangement to said guide roll and parallel thereto, said support beam having a longitudinal expanse, said support beam further having in said longitudinal expanse a contact surface for said adhesive strip, said contact surface being situated so that a holding slot for said adhesive strip is defined immediately therebelow and bordering on said contact surface, wherein a part of said adhesive strip protrudes from said holding slot, said holding slot being arranged generally parallel to the longitudinal axis of said support beam, said holding slot having a width dimensioned for the part of said adhesive surface covered by said protective foil, said covered part being adaptable to make a splice for said paper roll;
- a blade positioned below said holding slot, said blade having a cutting edge for severing a portion of said web from said paper roll;
- and
- blowing means positioned generally below the holding slot for raising said protruding part of the adhesive strip.
A device for the application of an adhesive strip on an end of a web wound on a paper roll, said adhesive strip having an adhesive surface wherein at least a portion of said adhesive surface is covered by a protective foil, said device comprising:
- a guide roll spaced from said paper roll;
- a support beam situated in closely spaced arrangement to said guide roll and parallel thereto, said support beam being pivotable about an axle and having a longitudinal expanse, said axle being arranged generally parallel to the longitudinal axis of the support beam and situated in closely spaced relationship with the guide roll, said support beam further having in said longitudinal expanse a contact surface for said adhesive strip, said contact surface being situated so that a holding slot for said adhesive strip is defined immediately therebelow and bordering on said contact surface, said holding slot being arranged generally parallel to the longitudinal axis of said support beam, said holding slot having a width dimensioned for the part of said adhesive surface covered by said protective foil, said covered part being adaptable to make a splice for said paper roll;
- a blade positioned below said holding slot, said blade having a cutting edge for severing a portion ofs aid web from said paper roll;
- a guide surface for guiding downward the portion of the paper web severed by the blade cutting edge, said guide surface partially surrounding said pivot axle and being situated in closely spaced relationship with the guide roll;
- and
- blowing elements for directing an air jet generally laterally and downward essentially toward the lowermost point of the guide roll arranged above the guide surface.
A device for the application of an adhesive strip on an end of a web wound on a paper roll, wherein a guide roll for the paper web is utilized to guide the web onto the paper roll, said guide roll being spaced from the paper roll, the adhesive strip having an adhesive surface wherein at least a portion of said adhesive surface is covered by a protective foil, said device comprising:
- a supporg beam situated in closely spaced arrangement to the guide roll and parallel thereto, said support beam having a longitudinal expanse, said support beam further having in said longitudinal expanse a contact surface for said adhesive strip, said contact surface being situated so that a holding slot for said adhesive strip is defined immediately therebelow and bordering on said contact surface, wherein a part of said adhesive strip protrudes from said holding slot, said holding slot being arranged generally parallel to the longitudinal axis of said support beam, said holding slot having a width dimensioned for the part of said adhesive surface covered by said protective foil, said covered part being adaptable to make a splice for said paper roll;
- a blade positioned below said holding slot, said blade having a cutting edge for severing a portion of said web from said paper roll;
- and
- blowing means positioned generally below the holding slot for raising said protruding part of the adhesive strip.
