<p>PURPOSE:To secure the steady running of the tape at the sucking time as well as prevent assuredly the damage at the tape tip, by forming the guide tube for the winding and running of the magnetic tape thick at the tape supply side and thin at the take-up side respectively. CONSTITUTION:The suction running is secured for magnetic tape 1 via blower 19 and sucking opening 20, and then mounted automatically and by suction to the fixed tape running path reaching take-up reel 8 via supply reel 6, tape supply side cylindrical part 14 each. In that case, guide tube 12 is formed thick at the tape supply side and thin at the take-up side respectively. As a result, the flutter frequency is increased at the tip of tape 1 although the air flow velocity is high at the area near opening 20, and the flutter amplitude is reduced extremely. As a result, the damage can be prevented assuredly at the tip of tape 1, at the same time ensuring the steady tape running at the sucking time.</p> |
