ROTARY PINCH ROLL LAMINATOR
for Substrate Lamination
A rotary laminator to exert bonding pressure to laminate two substrates
or web materials together. Accepts material up to 50" wide (Union
Tool laminators are available up to 62" wide.)
SYNONYMS
Rotary laminator, pinch roll laminator, substrate lamination machine
OPERATIONAL DESCRIPTION
The Union Series #15, 50" wide Rotary Laminator was designed to apply
bonding pressure for the purpose of laminating two substrates or web
materials together. Union Series #15 Rotary Laminators are available
in any width up to 62" wide.
This Series #15 RL pinch roll machine incorporates two 6-1/2" diameter
rolls with a 1" rubber covering. Both rolls are chain-driven through
a 1/2 HP variable speed motor. The upper roll is adjustable in relationship
to the bottom roll in a range from 0" to 4". A single handwheel raises
or lowers mechanical stops located on each end of the machine. Air cylinders
attached to the upper roll lowers the upper roll against these mechanical
stops so that an accurate gap setting can be made. A mechanical digital
indicator readout allows the operator an exact measurement of the gap
setting.
The 4" diameter air cylinders provide an adjustable amount of laminating
pressure up to a maximum of 1,300 pounds of pressure per cylinder at
100 psi. This relates to 52 pounds of line contact pressure per linear
inch of a 50" wide machine. 6" diameter cylinders are also available
for applications requiring even more pressure.
This laminator may be used in either a forward or reverse direction
and includes a selector switch to control the direction. The raising
and lowering of the upper roll is also controlled at the push-button
station mounted to the machine. The machine is complete with a disconnect
box. The standard voltage is 220/440 volt, 3 phase. The mounting location
of the push-button controls and gap adjustment wheel can be specified
by the customer.
A safety cable wrapped around the perimeter of the machine automatically
stops the revolving rolls and fully raises the top roll when activated.
Other features that may be added to this machine include unwind stands
(for roll materials), infeed and/or outfeed conveyors as well as rewinds
or sheet stackers.
