Equipment and method in handling of doctor blades for a paper/cardboard machine

A method for handling doctor blades of a paper/cardboard machine, said method comprising the steps of:

• supplying raw material for doctor blades to a doctor blade production plant;
• producing the doctor blades in the doctor blade production plant;
• transporting the doctor blades to a paper/cardboard plant;
• mounting the doctor blades to be used in connection with paper/cardboard machine rolls, where after use the doctor blades become used doctor blades;
• removing the used doctor blades from the paper/cardboard machine;
• packing the used doctor blades in storable form into a transit case according to the following steps:
• mounting the transit case to a reeling device having a support base, and a support arm which extends upwardly from the support base, an upper arm being mounted to the support arm, and a guide and a bolt being mounted to the upper arm, the transit case being mounted between a support on the support arm and the bolt;
• fastening the transit case to the upper arm with the bolt;
• guiding the doctor blades into the transit case with the guide on the upper arm;
• mounting the doctor blade to a boss on one end of a shaft mounted for rotation on the support arm;
• rotating a revolving frame mounted to the shaft opposite the boss to draw the doctor blade into the transit case guided by the guide on the upper arm;
• storing the used doctor blades in the paper/cardboard plant;
• transporting the used doctor blades away from the paper/cardboard plant;
• and
• delivering the used doctor blades into recycling, reuse or end use.

An apparatus for reeling used doctor blades to be in storable form for reuse, after-treatment or recycling of the doctor blades, the apparatus comprising:

• a support base;
• a support arm extending upwardly from the support base;
• a transit case detachably supported on the support arm, the transit case having a volume into which the used doctor blades can be reeled on a roll;
• an upper arm fastened on an end of the support arm;
• a guide mounted on the upper arm, the guide for guiding the end of the doctor blade into the transit case;
• a bolt on the upper arm fastening the transit case to the reeling device;
• and
• a support mounted to the support arm, the support for supporting the transit case to the reeling device;
• a shaft extending from the support arm and being rotatable thereon;
• a revolving frame fixed to a first end of the shaft;
• and
• a boss attached to a second end of the shaft.
