Tamp Pad Setup
Overview
All applicators with tamp units are supplied with standard tamp pads that are available in a
range of sizes and feature a predrilled hole design. This design allows them to be configured for
use with a great variety of labels starting with length and widths of one inch or more. Before
using, the tamp pad holes need to be "punched out" in a pattern to match the label size and
allow for proper application.
General Information
Use the following instructions as guidelines for establishing the hole pattern needed for a
variety of common label applications. The actual patterns shown may be reduced or enlarged to
work for your label size. The number of holes also may have to be reduced or increased to
maintain the pattern symmetry and proportion. If a mistake is made, the punched hole can
simply be covered with a piece of cellophane tape. (The tape should be put on the side of the
pad that mates with the manifold.)
Never punch out all the vacuum/blow holes! This would result in poor label feed and weak
label blow off. The type of application and the label size dictate the hole pattern required.
Punching Instructions and Safety
! CAUTION ! Disconnect the power from the AC power source.
Remove the tamp pad from the manifold.
Start by placing the tamp pad (hole side up) on corrugated cardboard that is
resting on a hard supporting surface.
Insert the "pin punch" supplied with the applicator into the selected predrilled
hole.
While wearing protective gloves and safety glasses, use a brass hammer (do
not use a hammer with a hardened head) to strike the punch and complete the
hole through the tamp pad. Repeat for all the holes in your pattern. Do not
turn the punch over as the end struck by the hammer will mushroom from
being struck by the hammer and get stuck!
Make sure that all slugs produced from knocking out the blind hole are fully
removed from the tamp pad BEFORE re-installing the tamp pad on the
manifold.
When the desired hole pattern is achieved, mount the tamp pad to the
manifold.
Note: Any slug that is not fully detached from the pad prior to reinstalling the tamp
pad to the manifold will become lodged in the pneumatic tubing or pneumatic values,
thus reducing available vacuum. Therefore, do not knock out any slugs with the tamp
pad still mounted to the manifold.
