Abstract: A squeegee or flood bar for the print carriage of a screen printing machine which consists of a mounting bracket and blade portion in which the bracket portion is adapted for quick attachment and detachment to the print carriage and the bracket is attached to the blade portion on one side of the blade portion. The bracket attaches to one face of the blade near the upper edge and this offset position means that a change in the angle of inclination of the blade does not result in a large change in position of the bottom edge of the blade. The attachment means is preferably a toggle clamp on the carrier bar for the squeegee and flood bar. By simply releasing the toggle clamp the bracket and blade can be quickly removed and replaced.

Abstract: A print arm for a screen printing machine of the type having radial print arms and radial pallet arms that rotate relative to the print arms the print arms incorporating a detachable print carriage drive assembly from which the print carriage is suspended the print carriage drive assembly incorporation an electrically driven belt to reciprocate the print carriage and the belt path is horizontal. In one embodiment a print assembly plate is provided as the base for the print carriage support assembly so that all the components are mounted to the plate and the plate can be easily attachable to the print arm. In a second embodiment a channel member is used in conjunction with three mounting plates instead of the one assembly plate.

Abstract: A quick release pallet for a screen printing machine in which the pallet for supporting an item to be screen printed having having a longitudinal axis a top surface for supporting a garment to be printed and an underneath portion for attachment to a pallet arm; a top plate of a porous material; and at least one key hole slot in the underneath portion of said pallet. The pallet arm supports the pallet along its longitudinal axis and has attachment means to cooperate with the underneath portion of the pallet. The attachment means comprises two fastening heads adapted to fit and slide in the slot in the underneath portion of the pallet and the fastening heads are able to be clamped against the slot to fix the pallet to the pallet arm. The advantages are that the pallet has no attachments and can be very quickly positioned and released. Because there are no screw holes in the top surface of the pallet it has a larger print area. The pallet can be modified to a vacuum pallet with a perforated or porous top plate.

Abstract: A carousel screen printing machine which includes a stationary column supporting a plurality of print heads; a rotatable carousel mounted on said column supporting a plurality of pallet support arms and drive means located at or above said carousel for indexed movement of said carousel about said stationary column. Indexation and registration is achieved using bushes on the carousel rotor to cooperate with complementary pins at an indexing station and at a registration station. The location of the motor makes the machine more stable during rotation and is easier to access. The registration and indexing system is simpler and uses fewer parts than in the prior art. In one embodiment an additional print head is used in association with a dual purpose load unload station.

Abstract: A transfer heat press which is intended for use with a rotary screen printing machine, incorporates a C shaped frame mounted on a support and moveable vertically relative to said support. A heater platen is mounted to the top of the C frame. A lower platen adapted to support the pallet of the rotary screen printing machine is mounted on the lower part of the C frame. The lower platen is moveable toward the upper platen. The lower platen applies a force to the underside of the pallet arm of a screen printing machine which results in the platen frame being allowed to move downwardly. This downward movement is guided and cushioned by a pneumatic or hydraulic spring. This arrangement means that the force on the pallet arm is equal to the weight of the platen frame less the upthrust of the pneumatic hydraulic ram. This reduces the risk of damage to the pallet arm.

Abstract: A quick release pallet for a screen printing machine in which the pallet has locating recesses at either ends which locate the pallet on the pallet arm of the screen printing machine by engaging locating lugs on the pallet arm. A toggle clip secures the pallet in position. The advantages are that the pallet has no attachments and can be very quickly positioned and released. Because there are no screw holes in the top surface of the pallet it has a larger print area. The pallet can also be modified to a vacuum pallet with a perforated top plate and a vacuum manifold below.

Abstract: A garment loader for a screen printing machine includes a carriage 37 which reciprocates between an extended position where a garment is fed into the jaws of grippers 42 attached to the carriage 37. The grippers are raised above the pallet 22 and the carriage retracts to the other end of the pallet 22 where the grippers 42 are lowered and release the garment which is now fitted on the pallet. While the pallet is rotated to the first print station the carriage is extended and the grippers lowered to be ready for loading the next garment.

Abstract: A screen off contact arrangement in which a rectangular screen holding frame [11] is adapted to secure the screen [13] on its two side rails [17,18]. Four off contact devices at the corners of the frame [11] allow adjustment of the off contact distance between the screen and the pallet. A scaled knob [33] enables incremental movement of the shaft [29] to move it relative to the fixed front and rear rails [15,16]. Each shaft [29] is secured to the ends of the side rails [17,18] so that incremental movement of the knob [33] results in movement of the screen [13]. The advantage is a simple repeatable manual adjustment.

Abstract: A screen printing machine having a rotor, a stator, a device for moving the rotor and stator into juxtaposition, and an annular track and track followers for guiding the rotor in vertical and radial directions.
