Embodiments herein describe a pneumatic mandrel for a packaging system. In one embodiment, the mandrel includes a pneumatic nozzle proximate to a loading volume in which items are disposed before being packaged. The pneumatic nozzle can contain multiple ports for directing airflow in different directions. The directions at which the ports generate the airflow may be selected to move items that may be stuck or snagged into the loading volume. Stated differently, the mandrel may generate airflows in multiple directions for pushing items towards the loading volume.

A mattress topper for fitting to a mattress may include a lower layer, a side layer configured to extend down along a side of the mattress, and an upper layer overlaying the lower layer and at least partially disposed between the lower layer and the side layer. The mattress topper may also include a seam including threads and extending along peripheral edges of the lower layer and the upper layer and extending through the lower layer, upper layer, and side layer, the lower layer and side layer bearing the threads of the seam. An air table may include a top panel including a plurality of vents extending through the top panel. A method of making a mattress topper with an air table may include lifting the mattress topper with the air table while performing sewing procedures on the mattress topper.

A separating device of an optical testing unit for testing rotationally symmetrical test objects includes two corresponding pocket wheels, each having a plurality of pockets distributed uniformly over a circumference. The pocket wheels rotate synchronously in opposite directions about parallel axes in response to a drive. A continuous conveyor transports the test objects on a transporting plane. Depending on the geometry of the test objects, the distances between the respective pocket wheels and between the pocket wheels and the transporting plane are determined so that the test objects, which are fed via and accumulating section, are moved between the pocket wheels while being guided by two pockets of the two pocket wheels and are released by the two pockets downstream of an engagement section. Once released the test objects are accelerated to a higher transporting speed in an accelerating section of the continuous conveyor and are separated as a result.

Apparatus for transporting plastic preforms, has a sorting device configured for sorting plastic preforms and a transport device arranged after the sorting device in a transport direction. The transport device includes a first support rail and a second support rail for carrying the plastic preforms between the first and second support rails along the direction of transport. The sorting device has two rollers spaced apart from one another, between which the plastic performs are guided. The apparatus has an adjustment mechanism for adjusting at least one lateral spacing of the support rails, wherein this adjustment mechanism has several adjustment units which are arranged one behind the other along the transport direction, wherein these adjustment units each enable an adjustment of the lateral spacing and wherein these adjustment units are mechanically coupled such that the adjustment units can be adjusted together.

A laser irradiation apparatus (1) according to one embodiment irradiates a workpiece (16) with a laser beam (15) while conveying the workpiece (16) caused to float with the use of a flotation unit (10). The flotation unit (10) includes precision float regions (11a, 11b) and rough float regions (13a to 13j). The precision float regions (11a, 11b) are configured to cause the workpiece (16) to float by utilizing ejection and suction of a gas, and the rough float regions are configured to cause the workpiece (16) to float by utilizing ejection of a gas without suction of a gas.
