Apparatus with zone coated transfer tape for separating and spooling a paper web

Abstract

The present invention relates to a paper web processing apparatus featuring a transfer tape construct designed for efficient turn-up operations. The apparatus includes a carrier paper with a zone coating applied in longitudinal stripes, an adhesive layer laminated to the carrier paper, and a cover flap that protects the adhesive from environmental contaminants. The transfer tape construct is mounted on an empty web spool, and the zone coating comprises a silicone-based release material. The cover flap is engineered to open in response to centrifugal and aerodynamic forces during spool rotation, facilitating the separation of the adhesive layer into ribbons along the zone-coated areas. This configuration allows the cover flap to bridge a gap between the empty web spool and a paper web, ensuring a seamless transfer process. The apparatus is designed to enhance the reliability and efficiency of paper web processing, particularly in high-speed environments.

What is claimed is: 
     
         1 . A paper web processing apparatus, comprising:
 a transfer tape construct, including:   a. a carrier paper with a first face and a second face;
 ii. a zone coating applied to the first face in a series of longitudinal stripes; 
 iii. an adhesive layer laminated to the first face; 
 iv. a cover flap positioned to protect the adhesive layer from environmental contaminants; 
   b. an empty web spool on which the transfer tape construct is mounted;   c. wherein the zone coating comprises a silicone-based release material;   d. further comprising a second zone coating applied to the second face of the carrier paper, the second zone coating comprising a series of longitudinal stripes that are offset from the series of longitudinal stripes on the first face;   e. wherein the cover flap is configured to open in response to centrifugal forces generated by a rotation of the transfer tape construct;   f. wherein the adhesive layer is configured to separate into ribbons along the zone-coated areas when the carrier paper is pulled;   g. wherein the cover flap is configured to open due to aerodynamic forces during the rotation of the empty web spool; and   h. wherein the cover flap is configured to bridge a gap between the empty web spool and a paper web during a turn-up process.   
     
     
         2 . The apparatus of  claim 1 , wherein the carrier paper is made from a pulpable material to facilitate recycling and environmental sustainability.

         4 . The apparatus of  claim 1 , wherein the cover flap is made from a flexible material that allows it to conform to a shape of the empty web spool during rotation. 
     
     
         5 . The apparatus of  claim 1 , wherein the zone coating is applied in a pattern that maximizes the separation of the adhesive layer into ribbons. 
     
     
         6 . The apparatus of  claim 1 , wherein the transfer tape construct is configured to be easily removable from the empty web spool after use. 
     
     
         7 . The apparatus of  claim 1 , wherein the cover flap includes a tab for manual opening to facilitate initial setup. 
     
     
         8 . The apparatus of  claim 1 , wherein the adhesive layer is resistant to airborne contaminants to maintain its adhesive properties. 
     
     
         9 . The apparatus of  claim 1 , wherein the empty web spool is equipped with a mechanism to adjust its rotational speed to optimize the opening of the cover flap. 
     
     
         10 . The apparatus of  claim 1 , wherein the cover flap is treated with an anti-static coating to reduce an attraction of dust and debris. 
     
     
         11 . The apparatus of  claim 1 , wherein the transfer tape construct includes multiple layers of adhesive to enhance its bonding strength. 
     
     
         12 . The apparatus of  claim 1 , wherein the zone coating is applied using a precision coating technique to ensure uniformity. 
     
     
         13 . The apparatus of  claim 1 , wherein the cover flap is designed to detach from the transfer tape construct after the adhesive layer is exposed. 
     
     
         14 . The apparatus of  claim 1 , wherein the adhesive layer includes a color indicator to show when it is fully exposed. 
     
     
         15 . The apparatus of  claim 1 , wherein the empty web spool is made from a lightweight material to reduce energy consumption during rotation. 
     
     
         16 . The apparatus of  claim 1 , wherein the transfer tape construct is pre-cut to a specific length to match dimensions of the empty web spool. 
     
     
         17 . The apparatus of  claim 1 , wherein the cover flap is reinforced with a mesh material to increase its durability. 
     
     
         18 . The apparatus of  claim 1 , wherein the adhesive layer is formulated to provide a temporary bond that allows for repositioning of the paper web. 
     
     
         19 . The apparatus of  claim 1 , wherein the zone coating is designed to degrade over time to facilitate recycling of the transfer tape construct. 
     
     
         20 . The apparatus of  claim 1 , wherein the cover flap is configured to fold back onto itself to minimize its profile when not in use.
