Abstract
Line-winding spool for grass-cutting heads, comprising a central body provided with a central axis of rotation coinciding with the axis of rotation of the grass-cutting head when inserted into it, said central body having a circumferential side area on which there is defined the annular area where the cutting line is wound, said spool having at least one channel crossing said central body transversally, provided with two openings on opposite portions of said side area for the insertion of the cutting line, said at least one channel having two opposite first segments starting from said openings towards the inside of the central body, and a curved connection segment between said first segments having a concave shape with the concavity upwards, said central body defining, in said concavity, a cavity, whose bottom is at a lower axial height than the axial height of said openings, characterized in that said curved connection segment has a lower surface that is substantially continuous along all its extension so as to be substantially closed downwards, with respect to the outer environment, to allow a single passage of the line from a said opening towards the opposite opening without the line exiting from said central body.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
