Abstract
Abstract A reel drum is rotatable in a predetermined direction to form thereon a plurality of juxtaposed coils from respective strips, pressure roll means are engageable with said coils to force the final convolutions of each coil against the latter. A plurality of dispensers are provided, each of which is engageable with one of said coils behind said pressure roll means when said drum rotates in said direction and adapted to dispense adhesive tape so as to tie said coil as it receives the trailing end portion of said strip.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A winding device for coiling a strap comprising a rotatable drum for receiving said strap, a first pressure roller engageable with said strap to force the final convolution of coiled strap against the coil on the drum, a dispenser of adhesive tape engageable with said strap and disposed behind said first pressure roller to dispense adhesive tape onto the coiled strap, a second pressure roller engageable with said strap and disposed behind said dispenser for applying pressure to the coiled strap, a primary pivoted lever disposed in relative position to said drum and movable to positions toward and away from said drum, an actuating cylinder for moving said primary pivoted lever, a secondary pivoted lever connected pivotally to the free end of said primary pivoted lever and adapted to carry said first pressure roller and said second pressure roller.
Claim 2
Dependent Claim
139 words
A winding device for coiling a strap comprising a rotatable drum for receiving said strap, a first pressure roller engageable with said strap to force the final convolution of coiled strap against the coil on the drum, a dispenser of adhesive tape engageable with said strap and disposed behind said first pressure roller to dispense adhesive tape onto the coiled strap, a second pressure roller engageable with said strap and disposed behind said dispenser for applying pressure to the coiled strap, a primary pivoted lever disposed in relative position to said drum and movable to positions toward and away from said drum, an actuating cylinder for moving said primary pivoted lever, a secondary pivoted lever connected pivotally to the free end of said primary pivoted lever and adapted to carry said first pressure roller and said second pressure roller.
Claim 3
Dependent Claim
139 words
A winding device for coiling a strap comprising a rotatable drum for receiving said strap, a first pressure roller engageable with said strap to force the final convolution of coiled strap against the coil on the drum, a dispenser of adhesive tape engageable with said strap and disposed behind said first pressure roller to dispense adhesive tape onto the coiled strap, a second pressure roller engageable with said strap and disposed behind said dispenser for applying pressure to the coiled strap, a primary pivoted lever disposed in relative position to said drum and movable to positions toward and away from said drum, an actuating cylinder for moving said primary pivoted lever, a secondary pivoted lever connected pivotally to the free end of said primary pivoted lever and adapted to carry said first pressure roller and said second pressure roller.
Claim 4
Dependent Claim
139 words
A winding device for coiling a strap comprising a rotatable drum for receiving said strap, a first pressure roller engageable with said strap to force the final convolution of coiled strap against the coil on the drum, a dispenser of adhesive tape engageable with said strap and disposed behind said first pressure roller to dispense adhesive tape onto the coiled strap, a second pressure roller engageable with said strap and disposed behind said dispenser for applying pressure to the coiled strap, a primary pivoted lever disposed in relative position to said drum and movable to positions toward and away from said drum, an actuating cylinder for moving said primary pivoted lever, a secondary pivoted lever connected pivotally to the free end of said primary pivoted lever and adapted to carry said first pressure roller and said second pressure roller.
Claim 5
Dependent Claim
61 words
A winding device as claimed in claim 1, comprising an associated pivoted lever connected to the free end of said secondary pivoted lever and adapted to carry said dispenser, and an actuating member acting between said secondary pivoted member and said associated pivoted lever for moving said dispenser into and out of position with respect to the coil of the drum.
Claim 6
Dependent Claim
44 words
A winding device as claimed in claim 1, comprising spring-loaded bolt means disposed between an intermediate portion of said primary pivoted lever and the free end of the secondary lever for maintaining a pressure on the pressure rollers when in engagement with the coil.
Claim 7
Dependent Claim
47 words
