    • 专利摘要:
    The present application relates to a liner for magnetic tape cassettes comprising a sheet-like element (1) insertable between the axial ends of the reels (6) of magnetic tape and the inner walls of the box-like shell (5) of the cassette (4) and defining a pair of through holes (2) located at the hubs (3) of said reels (6). The sheet-like element (1) defines at least one centering ridge (10) with high elastic rigidity which engages at least partially with the peripheral region of the axial ends of said hubs (3), for centering of the hubs with respect to the middle plane of the cassette (4), and at least one alignment ridge with very low elastic rigidity engageable with the longitudinal edges of the magnetic tape, for aligning the windings of the reel of magnetic tape (6).

    Claim
    A template for 25 magnetic tape cassettes containing a leaf-shaped element with profile protrusions and a pair of through holes located in the core region of the magnetic tape coils, wherein the leaf-shaped element is installed between the axial ends of the magnetic tape coils and the inner walls of the cassette box, distinguishing with the fact that, in order to simplify the design and reduce friction, at least two profile protrusions are made on the surface of the sheet element, one centering and the other leveling, elastic stkost last less elastic stiffness of the centering protrusion profile, each of the protrusions is parallel to the longitudinal naprav20 leniyu sheet member, and in places of through holes tangentially or obliquely, the height of the protrusion with respect to the alignment plane of the sheet member is proportional to half the height of the inner cavity of the cassette,
