ABSTRACT:
This apparatus is an automatic winder of roofing material utilizing hydraulic power to operate pull rollers at increased speed; to operate a knife and anvil with greatly reduced shock and noise; to enable a high speed mandrel to be loaded and unloaded more accurately and more rapidly while minimizing misfeed occurences; to provide for automatic shutdown in case of malfunction, to isolate the sheet material from all but the pull rollers and the mandrel while the winding operation is in progress; and provide a sound reducing hydraulic reservoir within the frame of the machine to absorb shocks and noise. Accommodation for minimum flexing of the sheet material is provided.
This invention is directed to an automatic hydraulic roll winder, and more particularly, to an apparatus for automatically winding, measuring, cutting, and removing web materials using hydraulic power.
