The present application discloses a coating method including: detecting a shape of an object over a coating zone which extends from a start point position to an end point position to generate first detection data before application of coating agent to the object; moving a bracket for holding a nozzle for discharging the coating agent with bringing the bracket into contact with the object to apply the coating agent to the object over the coating zone; detecting a shape of the object after application of the coating agent over the coating zone, to generate second detection data; extracting first extraction data and second extraction data in correspondence to detection positions intermittently set in the coating zone from the first detection data and the second detection data; and comparing the first extraction data with the second extraction data to detect a coating state of the coating agent.

A preform coating device is provided with: a rotational holding part that horizontally holds a preform and rotates the preform about the axis of the preform, and that grasps a spout of the preform; a conveyance part that conveys the preform by moving the rotational holding part; a dispenser that discharges a coating liquid toward the preform; a preform support part that supports the bottom-side end of the cylindrical barrel of the preform while the dispenser is discharging the coating liquid; and a spout support part that supports the outer circumferential surface of the spout of the preform while the dispenser is discharging the coating liquid.

An arrangement in a curtain coater for starting and stopping coating of a web, having a reservoir and a connected surface extending over the web toward the curtain to collect the coating as the coater moves over the web to start coating the web. A cover plate that swing around a cross-direction shaft connected to the cover plate. In one embodiment the shaft also moves in the machine direction. The cover plate is used to protect an leading edge of the collecting surface from being covered with coating and pivots to be cleaned with fluid which may be supply from the shaft. The cover plate is arranged so the fluid drain off the cover plate onto the collecting surface or reservoir. When clean, the cover plate is repositioned to protect an leading edge of the collecting surface during the next start or stop operation of coating the web.

A hot melt adhesive supply system is disclosed. The hot melt adhesive supply system includes an outer container defining an upper cavity and a lower cavity. The upper cavity includes an inner container having a top opening to receive unmelted hot melt adhesive pieces and a bottom aperture. The system also includes a dispensing mechanism between the upper cavity and the lower cavity. The dispensing mechanism regulates the dispensing of the unmelted hot melt adhesive pieces from the upper cavity to the lower cavity. The dispensing mechanism includes a base plate and one or more rotating members that rotate to move the unmelted hot melt adhesive pieces through a gap defined between the base plate and the bottom aperture. The system also includes a transfer conduit that communicates the unmelted hot melt adhesive pieces from the lower cavity to a hot melt adhesive melter.

The invention relates to applying a liquid to pasty hot-melt adhesive to a substrate (44), comprising a template (29), having at least one cavity (38) for the hot-melt adhesive, and also comprising an adhesive-transfer infeed (33), which is assigned to the template (29) and through which the adhesive can be introduced into the cavity (38). The special feature consists in that the apparatus (10) further comprises a transporting-fluid-supply opening (35), assigned to the template (29), and a device for displacing (13, 15), in particular pivoting, the template (29) between a first position, in which the cavity (38) is assigned to the adhesive-transfer infeed (33), and a second position, in which the cavity (38) is assigned to the transporting-fluid-supply opening (35), and therefore the adhesive, in the second position, can be discharged from the cavity (38) by a transporting fluid flowing through the transporting-fluid-supply opening (35).
