Straight arm This configuration allows two molds or spiders (a framed group) of molds to be mounted directly opposite to each other on either side of the central concentric shafts. This can allow a large number of small parts to be mounted simultaneously within the two rotating volumes as shown in Fig. 15.15. 

Pests such as aphids, whitefly, and red spider mite use needlelike mouth-parts to pieroe plant stems and suek sap, resulting in redueed vigor and growth distortions (as in aphid damage, shown here). Baeterial infeetions ean also enter the plant via the wounds. Sapsuokers oan transmit viruses, and their waste (honeydew) provides a food souroe on whioh molds thrive.

Mounting one mold on the arm is fairly straightforward. Multiple molds require careful design for mounting on a single spider. Improper mounting can result in an abnormally high rate of wear and tear on the mold and excessive flash formation on the part.
